Changing in game resolution - Android Software/Hacking General [Developers Only]

Right I've searched far and wide for a solution to this problem. I've got one of those new android 7 inch tablets. but being one of those cheapy unbranded things there is nout on the web about them.
Basically when i play games it has to scale them to the 7" screen and it just cant cope.Not even with stretching basic gameboy colour games. (that'll teach me for being cheap!) So i was wondering, if like on pc games i could lower the resolution which I know would fix the problem.
Im running android 1.6 if that helps at all

Game emulators - performance

Hi,
i just wondered about the Touch Pro's performance since it has more memory or isn't it significant enough?
Can you run PS-games smoothly?
What about SNES/GBA-games?
And with a keyboard it should be more fun to play with.
But i have heard about problems about it.
If you slide the keyboard out it automatically switches to parnoma-mode and you can't even start your programmes....
Also one further question, what do you think?
Iphone3G vs. Touch Pro
On which device will the games run more smoothly?
I have watched some youtube-vids of some ps-games on the Iphone, but it was just horribly slow.
Well considering the hardware , CPU:624mhz and a gpu, i just can't imagine that it will run better on the Pro, or?
The iPhone CPU is underclocked by a fair amount to conserve battery power.
What, really?
Even with applications on?
And what about the HTC Touch Pro, ist it also underclocked?
I have read something like about 25-30fps, and what i have watched on Youtube with Iphone, it was never 25fps.
SNES/GBA-games run fairly well on the HTC Touch pro, but still a bit slowish.
Most of the Playstation roms i tried crashed, but the few that did work also are slow.
But 25-30fps? no way - not even close. where have you read that?
I have the feeling that the 640x480 resolution sucks the performance out of a lot of games, compared to a 400mhz 320x240 device.
Also the hardware buttons are - although stylish - complete crap for playing games, so you have to use the on-screen controls or us the slide-out keyboard.
Clearly, the Touch Pro is not a gaming device
I have read it in the Diamond forum.
Can't you lower the resolution?
Hm, Perhaps i should get the Omnia with its low resolution^^
But which one has the better GPU?
I mean, all of the three have dedicated GPUs.
It's a pity because it is "only" a problem of the software (emulator).
I mean with PSP, you can run PS/SNES/GBA-games.
Has anyone tried Enigmo with the T PRO?
It's a 3D accelerated game my friend showed me on his Dell Axiom v50
Meh.
I don't wanna buy an almost 1000$ now.
Just the emulators aren't good enough.
I will buy cheap and good mobile phone and a PSP.
I thought i could get everything in one device....
Hm, Perhaps i should get the Omnia with its low resolution^^.

With the Omnia you will definetively have better performance (lower resolution, faster cpu).

That doesn't matter for emulation, they are not using it!

It's always a great difference, if you program for a specific hardware or for an operating system. e.g. console - pc
So, how hard would it be to rewrite a current emulator to utilize a gpu? Specifically the SNES emulators, it looks like they haven't been touched in ages and they have always been generally slow.
There is a Snes emulator that uses the Diamond GPU...
there is? do you have a link/name of the emulator?

It's just not fair to say that and not tell us what that emulator is, LOL.
I've been a little disappointed in the Touch Pro's performance with emulators - but I kind of expected that. VGA screens are very slow for emulation, though they do make games that aren't even designed for that resolution more stunning. IE - Contra for the NES looks better on my Touch Pro than my 6700 (QVGA).
However, nes on smartgear is nearly fullspeed (disappointing that it's not . . .), Turbographics is also close to fullspeed, but occasionally has jittery play. Genesis on picodrive is smooth, but not 100% speed - occasional slowdowns. CPS1 & 2 games on Finalburn are very smooth, but again - just a little too slow. I haven't gotten neo geo games to work at all for some reason.
I'd originally wanted to connect my phone to a tv and play from my couch, but I think performance would be completely too slow.

Anyone know what this emulator is? Does it exist?
I can´t remember the name but it uses open gles which should be supported because Call of Duty Open Gles version runs hw accelerated.

I got metal slug to work and it runs very well. Are they not showing up or just not running? Ghost and goblins runs smooth too.
P.S. what emulator are u using for nes?

Why do you guys always link VGA to slow? So wrong...
Dell Axim x51v has an VGA screen. Performance? Google it. And it's a PPC from 2005.
Anyway, it would be nice if someone, who played a bit with emulators, will construct a list with TP-compatible emulators.
I haven't been able to get a cache to build. I'm trying again now, so hopefully I can get even ONE neo geo game to load, LOL.
*edit: I was able to get neo geo roms to run. I don't think a cache will build with kfortouchpro running in the background. The cache builds very fast after that. Unfortunately, performance is a little sluggish with sound enabled.
For NES it's Smartgear. I payed for it (I think $10), since it has the distinction of being by far the best TG16 emulator for PPC. It also emulates gb, sms, and genesis without all sound features. Also it had been reported to work best on VGA devices.
If anyone knows the name of the SNES emulator - I know a lot of us would appreciate knowing. SNES has always been sluggish, even on faster QVGA machines.
I was wondering if remapping programs make any difference in being able to map buttons for emulators such as PocketCultMAME and pocketgnuboy. I would really like to be able to play games in portrait mode rather than in landscape. Has anyone got either of these emulators to work on the Fuze in portrait mode?
I have no prob playing gba/neogeo/snes with keyboard using kfortouchpro.
For gba, I get near-30 on some games (super robot wars, for example) while unplayable sub-5fps on others (need for speed).
Neogeo is consistently around or above 20fps (mostly action/platform, and things like marvel vs capcom work too).
Genesis works around that fps, although not the fastest.
Snes is a different story. It's much slower, but I found final fantasy 6 to be playable with some adjustments to frame skip. All that is without sound, btw.

Windows Phone 7 games less fps?

Anyone else notice this? Doodle jump and fruit ninja have less frame rate than in IOS. It may be not much of a big deal for you guys but for a mobile/console gamer like me it is.
yea I noticed that too...
I never played either of these games on iOS so I can't say, but for me the fps is fine even for PES2011. Ive played the same games on Android and don't see a noticeable fps difference.
I just hope they get rid of the random lags in games come Mango, cause that's a serious issue that deters from the overall smoothness of WP7.
Hi, I own a HTC Mozart and a 3rd gen Ipod Touch (same hardware as IPhone 3GS), and this was one of the first things I noticed when playing games on my new WP7 phone.
Simple games like Doodle Jump, Angry Birds and Fruit Ninja all run fine but at a noticeably lower framerate. If you haven't played both it doesn't really matter, but when comparing wow the iOS versions are so much smoother!
A more demanding game is "I Love Katamari". This uses simple textures but pushes alot of polygons and has alot of objects in the world - enough to make it totally unplayable on 1st and 2nd gen IPhones. Comparing the game on both systems, again iOS runs it significantly smoother, and also has a better font and transitions in the menus. The HTC is obviously rendering at a higher resolution, as there are alot less polygon "jaggys".
What worries me is the 3rd gen IPhone is now 2 years old, which is an absolutely lifetime when i comes to mobile hardware, and has an almost 50% slower CPU. Yet it still outperforms the latest WP7!
It can't be a hardware issue, so maybe its the OS - can anyone offer any insight?
please use your brain!
iphone 3g screen resolution: 480 x 320
WP 7 screen resolution: 480 × 800
clear now?

Not really.
Doodle Jump is a very simple 2D game, yet it suffers the most obvious framerate drop. Are you saying it's just not possible to produce 30FPS on a WVGA screen with the 1st generation of WP7 hardware? If so that's a pity.
Resolution hasn't got too much to do about this, I think. Best bet is that the framework used on wp7 is more high level and if you want to squeeze more fps you have to work the plumbing.
If you look at games like The Harvest, it's damn smooth even compared to a piss-poor 2D game like Doodle Jump. There are Doodle Jump clones in the market which have better framerate.
Overall, I would say it's just the platform which is new.
The fact that half xbox titles are just bad and some are totally buggy, but many others are excellent, tells you that it's feasible. Maybe people need to familiarize a bit more with the platform.
Just lazy ports.

I just love when people say what I wanted to say with 1/100 words
The current version of WP7 (NoDo) limits 30 fps in their games. Mango will up the FPS limit to 60 fps. I read somewhere that Doodle Jump will get this treatment and will be as smooth as a babies behind once mango is released..along with a number of other games I guess.
In order to stabilize, ms limit fps

finding the right tablet for me on the cheap?

I've been wanting to get my feet wet in android tablet land for quite some time. I would like the following features:
pdf/ebook reading with bookmarking / highlighting / notes
GPS (I already have a bluetooth gps module if that helps) for dash-mounted in-car navigation
bluetooth keyboard support (official or unofficial i really don't care but it's got to be there).
fast web surfing / display effects
the ability to run honeycomb (even if it's unsupported)
preferably some kind of decent camera on for skype / snapshots though i suppose i could do without it...
I have not yet fully decided on a 7" or 10" tablet but I would find some additional convenience with the smaller of the 2 as I plan to do some reading on this. also, as I will be doing lots of reading, I need a display resolution of at least 1024x600 and aprox. equivalent dpi or better for 10" tablet.
I've looked at the nook color and it seems like a really nice tablet but it seems kind of sluggish for the really high price of $250... if i could find one of these in the $150-200 range I could probably be convinced to go with one of these.
I've also looked at the viewsonic G tablet and was impressed with the underlying tegra2 hardware but very disappointed with the display viewing angle, and to a slightly lesser extent display resolution. I think it's going price of ~250 would be warranted if the display were actually good (high resolution and good viewing angle).
Does anybody have any other ideas for very inexpensive, high resolution, fast tablets that I should be looking at, or perhaps some kind of epic deals? (i'm ok with used if i could find something i'm happy with even).
Thanks,
Cpgeek

Surface Pro game scaling?

Hey guys
I recently purchase the 128gb surface pro and have tried playing a few games. One of them is BLack ops 2 which doesn't run horrible, but I think it would run better in 1366x768? When I change the resolution it just makes the screen smaller instead of scaling it full screen. How do I do this? I heard you have to install the graphics drivers which I did but I don't see the setting that I need to fix this.
Download the Intel Graphics HD Driver and you shouldn't see black bars anymore. However, in some games, you'll still see black bars. I haven't figured out a way around that yet =/

it looks like you have to change the resolution on the desktop before launching the game. At least with black ops 2... unless there is something I am missing.

Horrible screen banding on new shield k1

Hello everybody
I recently picked up new shield tablet k1 and played with it a bit until i noticed something strange i didnt experience with my other tablets - banding. Everything looks OK if you browse photos, websites etc, but any 3D game shows horrible banding in place of gradients. Im running stock kernel with OTA 1.2, no idea if it happened with 1.1 because i updated right away after first booting my tablet. Also checked every possible colour settings, force gpu rendering, wipe erase data and reinstalling it all also makes no difference.
It doesnt look like screen issue because gradients on lcd test websites look great. I'll pick some screenshots later when im back home to show my issue, just wondering if anybody else had the same problem and any tips are very welcome.
Could you give us some examples of games that show this problem? I personally haven't ever noticed this, but I'll try some new games (to me anyway) and let you know if I have the same thing.

It happens for example in Simcity Buildit, where its most noticeable on loading screens, but with closer look also on gui elements. Also in games like Rayman Adventures, Marvel Contest of Champions or Modern Combat
Here's screenshot from Simcity loading screen
Code:

Same here but I only notice it when using full brightness.
I think the developers use only 16 bit graphics. That in combination with the large full hd screen makes that more noticable than on larger screens.

This makes no sense as those games are supposed to be optimized for shield, developers would have to forcre 16 bit rendering for Tegra exclusively. Those games look better on much weaker devices.
Hi, I have also this problem playing Minecraft, Geometry Dash and the same Rayman Adventures. I thought it could resolve with a wipe but nothing. Strangest thing I noted is that is a software problem, since you can see those bands also in a screenshot or in a screen cast.
Probably we have to report to nvidia as an issue of the last ota
Did you contacted them?
I didn't contact them yet because im trying to gather more information, at first i thought its issue with my device but it seems this affects more tablets.
I did some tests. Seems like grey scales are more affected, but also other colours have this banding. I tried the same tests on Motorola Moto E and LG G3 and there aren't band. But doing a screenshot i can see the band in other phones too.
I don't know if this happens also on other firmware version or on custom ROMs.
I tested this with stock Android 5.1.1 and there was the same issue, so it's not ROM specific. Also worth noticing is the fact that all gradients look very good on images or websites. I'll try to test this with GLTools faking GPU info, the same trick allows Tegra to run properly XCOM: Enemy Within without graphical glitches.
If your tab is rooted, can you test if this happen in custom ROM too, or with a custom kernel? Maybe is nvidia fault.
However that is the weirdest. If I remember right, photos and web navigation aren't drawn by GPU, differently from games and particular test images, I don't want to say a stupid thing though.
Since I didn't rooted yet, principally for warranty reason, I have to wait any fixing ota, hoping that it isn't hardware fault
I tested it with GLTools faking GPU info with no positive result, so the last possible test is custom kernel and custom rom.
EDIT
Unofficial Kernel changed nothing. Didn't try with custom ROM yet and at this point i think its pointless. All seem that its Tegra driver behavior and unless it gets updated we have to stick with what we've got.
I believe I have the answer : the precision of the hardware (or firmware) texture interpolators is way lower than on other platforms. Maybe something like fixed point 24.2 instead of 24.8. See for details first result on google (I can't post url...) : "iq hardware interpolation"
I had extreme banding on a bloom FX on HP Slate 7 extreme only (tegra, was working fine on Nexus 5 (adreno gpu) and PC (GTX970)), on a dark orange gradient. I switched to manual interpolation in the shader, and the problem was gone. So I doubt the issue can be fixed with an android update, maybe a driver update, or maybe not at all as it could be hardware design, to improve performance (but at what cost !).
