What is your favourite s-pen response combination in both rom-wise and software-wise? I use Inkredible and cm13 rom, but there seems no difference. I am looking for both pretty looking (low resolution is not quite pleasent to see) drawings and low delay when I draw. Any suggestions?

Hi all, Got a Desire HD and a radio control helicopter (Trex 500).
Would like to be able to look at the heli in flight with the camera (in video mode is ok) and see what speed the rotors are spinning at.
All that's required is a method of adjusting the camera shutter speed while pointing at the heli until the blades look stationary. (Maybe use the volume rocker for adjustment)
Also a little routine to put the revolution figures on screen.
The heli blades should spin at about 2700rpm but for a wider variety of helis, would like to read a range from about 1900 to 3200 rpm.
A shutter harmonic frequency could be used as I dont think the shutter can operate at these speeds.
There are units available that use this method... But the mobile phone with camera already has the hardware needed. Just need a little bit of programming, I'm guessing.
If anyone can help i'm sure there would be a lot of interest from various fields....
Feedback on the idea welcome.....

PS. Thinking of existing measuring apps available, any reason why shutter speed can't be added to give object speed calculation and result etc etc
PPS Recording the heli in flight and then applying the Tachometer software would be ok.... might be easier to adjust the shutter speed for the video recording... ???
To measure the things like fan, you could simply add tachometer app for iOS on your iPhone. The fan blades will chop the light signal to provide the measurement. I would say very need app to have around. Search "Tachometer App for iOS"
I was testing out the HDR options for this and they do not seem to do much at all. There is a difference, but it is VERY minor. I took a shot without HDR, one with HDR, and then one using the free HDR app, and the HDR app simply blew the HTC HDR mode completely out of the water...
Has anyone else had any experience with this? Is there something I may be missing?
HDR always seemed like something better left to photo editing software to me (like photoshop). Phone camera filters always seem kind of lackluster, but then again, none of us are taking professional shots with a cell camera I assume
On topic though, I wouldn't doubt it being better. Sense stuff isn't exactly always perfection as far as software quality and HDR was probably just an afterthought tied into the camera so they could tick off a notch somewhere on some sheet for features.
Absolutely the same as my experience. I used HDR Camera from the market before this (free), and I really loved its results. When I installed the 3.0 Sense camera and saw the HDR setting, I was happy until I tried it. My theory is that it is NOT taking multiple pictures, but only doing an image adjustment --->> NOT the same thing. HDR Camera doesn't have the issues that some of you described. You do not have to be rock steady and my phone is plenty fast enough to take the three photos within about a second. The image settings are also adjustable (color, etc.).
On the other hand, the panorama mode in the Sense camera is Awesome!

Software cannot do what HDR does. HDR takes 2 pictures, adjusting the gain on the sensor between low and high. It combines the best of both images to gain detail in low light areas and avoid over exposure in high light areas. Software will not work after the fact because the extra information gained from low/high gain is not present. Unfortunately the HDR option is poorly implemented by HTC. If you try HDR on the Iphone, you can see a drastic difference.
Actually, I use Pro HDR on my Evo, and it takes fantastic pictures in true HDR. It is a touch slower than a pro camera, but it does actually meter the scene and adjust the camera's aperture accordingly. It then allows for adjustments between the composite image and allows for saving the final as well as the source images, meaning you can do further editing elsewhere. Outside of some cropping, I haven't had problems.
With that said, I would be curious to know what the deal is with Sense. What's interesting is if you put it in HDR mode, it shows the little icon in the top right with multiple images...like whoever designed it at least understood how true HDR *should* operate. Then, if you push and release it instead of the regular shutter button, it beeps and you hear the lens go, and the image focuses itself. So...idk. I don't see a noticeable effect in the regular images at all...
Hi All,
I'm generally pleased with the performance of my Surface Pro and since the 8.1 upgrade my graphics card performance particularly in games has been stellar.
I do have one issue which is in win 8 when a game ran in a non native resolution the graphics card would scale the image to be full screen automatically. Since 8.1 I seem to have lost this functionality and most games and my citrix work log in only keep the resolution but draw big black borders around it when going full screen.
Are there some better drivers for the inten 4000 series that work well? I'm reluctant to try various version floating around the net as when I did this on Win 8 I had terrible graphics performance and couldn't get back to the original drivers without a full restore.
What is the best procedure for rolling back drivers to the OS inbuilt ones?
I've had the same issue with my Surface Pro 2, the only "solution" I've found is to set the display resolution in Windows to something lower than native, like 1600x900, then launch the game, and it should scale to full screen properly, no matter what the resolution is set at. Obviously a better solution would be much nicer, but this is the only thing I've found that works.

Thanks I've gone back to the 3316 dirvers from microsoft and these give better fps in some games. But the problem still persists so I'll try your solution! :good:
Yo fellas, its your"rooting enthusiast SenpaiYank (lmao rooting enthusiast, as if such a thing exists)
Well, as you know, our device has a quite outdated and not so beefy (at all) SoC, the snapdragon 625. While its CPU is not tremendously ridiculously bad, the GPU quite is. This is not a prolem to people who don't care about games but a very prominent one on the other side.
With the help of this trick, tweak, whatever you decide to call it, you'll practically be able to play any game out there that you're not able to or play that same game at a higher setting than you would. The trick consists basically on lowering the screen resolution through a script, trading some of the visual quality for a noticeable night day performance boost. It's a common trick that works on other devices too and I've yet to find a game that had problems with it.
I'm using "profile" scripts to achieve it so you can change it on the go. I feel that way is the most ergonomic and quick one. Just run each script with root permissions according to your need. I recommend FX file explorer. Wanna play a graphically intensive game? Switch to gaming profile. Wanna do something else besides gaming? Switch to the default one.
As I side note, the trick can be done on unrooted users too but you'll need a computer and you'll have to apply the gaming profile permanently (unless you're willing to repeat the procedure whenever you want to go back to default). I can talk about it if you guys get interested on it.
Enough blah blah, how do I do it ?1st - Grab both of them (default.sh and gaming.sh)
2nd - Install (in case you don't have it), open and type this on the Terminal Emulator app:
Code:
su
To attain root access (not sure if needed but, just in case)
Code:
wm density
To get your current screen density value at 1080p (override density field).
Lets imagine you got 432.
3rd - Choose and calculate a new resolution for your gaming profile
So now lets ge to the actual work. Our device native resolution is 1080p (1920x1080) and we want to lower that.
I lower it to 810p (not a standard lmao) which is 75% of 1080p (1440x810) as it gives me agood balance between visual quality and performance. You can go even lower to something like 50% if you're ambituous about performance. At 810p I can expect a minimum of 25% performance uplift (not FPS).
So, to get your gaming profile resolution DPI, you multiply the relative percentage of it by the default profile resolution DPI.
Code:
[COLOR="darkred"]432[/COLOR] * [COLOR="RoyalBlue"]0.75[/COLOR] = [COLOR="Blue"]324[/COLOR]
This value will be your gaming resolution DPI a.k.a. the resolution from your gaming mode script.
4th - Edit default.sh and gaming.sh, apply the new values and save the files somewhere.
default.sh script should contain the values of your default resolution, in this case, 1920x1080 and 432. Size for resolution and density for DPI.
gaming.sh script should contain the values of your gaming profile resolution, in this case, 1440x810 and 324.
VOILÁ
To make the process much much easier and quicker, I use FX file explorer and its shortcut feature so I can switch between both profiles from my home screen pretty easily. Whenever I'm not playing a demanding game Is stick to the default mode, whenever I'm playing a graphically intensive game, I switch to the gaming mode and enjoy the improvement.
Cool, cool. So, is there an actual improvement in performance or is this just one of these so called placebo tricks ?It's definately not placebo and probably the most effective way around of increasing gaming performance!
I've tried to record a test with and without the trick (and failed, it doesn't look as effective in the video but I'll leave it here anyway). Take it with not 2 but 3 grains of salt due to all the uncontrallable factors that involved the scene, the actual gain in practical use is much more noticeable. The benchmark takes place in the super duper hot (pun intended) looking and intensive game, Shadowgun Legends.
On the first video, the device is running the Extreme Kernel, without the tweak, along a CPU cap of 2.5Ghz and a GPU cap of 855Mhz (or something around that). I didn't increase it further to prevent the device from overheating (which it already practically was) and because at a higher GPU clock, I would get arctifacts (my device does not support the 922Mhz frequency).

On the second video, the device is running a beta batch of the velocity kernel, with the tweak, along a CPU cap of 1.9Ghz and GPU cap of 672Mhz. I ran the device at a lower speed so you can see how useful the improvement can also be.

I ran the game at the high graphical setting (30 FPS max) on one of its most intesive scenarios and were at very high ambient temperatures (30C) so again, take the videos with a grain of salt. Used an external gamepad to play and used Scrcpy to record the screen (through wifi so, the quality and framerate from the recording is considerably worse than the actual one). You should also remember the 5-6 FPS strain of capturing the screen.
I also used game bench to monitor the framerate (top right corner) where the last 1 minute of each benchmark were with the screen capturing off. Once again, sorry for the bad quality of the recordings, I'll leave a screenshot of the game bench results.
Not willing to write a outro so, yeah, basically thats it
Here's another sample video, of the same game, this time at medium settings. Along the very noticeable smoother gameplay you can also notice how the GPU load goes down from 95-100 to 70-80 and it becomes less of the bottleneck on the scenario. With the gaming profile could I could actually remove the 30 fps cap and run the game at +30.

After mucking around with certain games I used to have on my old Galaxy S8 I've discovered something interesting. I get ridiculous lag and frame pacing in just about every game leading to poor results in games such as Cytus 2 (fast paced rhythm game relying on accurate input with no lag) the new Sky game (stutters and tearing in both refresh modes), and a side scroller that has no heavy graphical fidelity (lags on screen and even tears sometimes).
This is all kind of in accordance to this recent review video of the p40 (different phone, same chipset)
https://www.androidauthority.com/huawei-p40-vs-galaxy-s20-plus-1133345/
Now one thing I've noticed is that if I use appassistant to launch these games, the poor performance disappears entirely. No lag anywhere, in Cytus, where before during fast sections it wouldn't even register taps 6-7 times per song, there are ZERO misses across the board. Similarly, no screen tearing or lag in any other game.
Wondering if the OS is optimized to cut power to the GPU and put it into limp mode during normal operation to save battery as I've noticed a dramatic difference in battery drop when using appassistant or not to play games. I mean naturally, the appassistant game center is doing its job but man that's a big difference.
Anyone have similar experiences?
Whats appassistant????
