GPU load only 72% Nvidia 780M -> Solved

[aeldryn]

Hi,

I have a problem regarding a laptop ASUS G750JH with 780M GPU. On my desktop pc, when i run resolume without any layers active, the GPU load is on 99 percent, but on my laptop is around 50.

I think this is some kind of problem. FInally it causes when layers are active, output set, that GPU load stops at 72 percent, so the GPU performance is not fully used.

Anyone can help?
Thanks

So after trying all kinds of Nvidia Driver versions I finally get to the solution, which is somewhere else.

For the maximum usage of 780m GPU you have to set "Max Pre-rendered Frames" in the Nvidia Control Panel to number 4. Below are the screenshots showing the effect. Before this modification Resolume was under load using only 75 percent of GPU performance. Now almost 100 resulting in 20 fps increase





note that this last composition was specially made to test performance with enormous number of effects. In my normal use - FullHD + 17 layers of sources and routers it doesnt drop below 58 fps. Therefore I can also report that laptop with 780m is powerfull enough to run high resolutions compositions without problem.

If I'm not mistaken, setting "Max Pre-rendered Frames" to "4" will give you some latency, so if you use audio or cam capturing this is not recomended.

BPM: will test the latency difference - if it is noticable. However I did not found any other steps to force the GPU to use its all performance than this...

just tried this yesterday with a 650m on a laptop....
frames dropped up from 40 to 75 fps (also did some other settings cause it wasn't set there before)

i did'nt noticed a latency problem, but also did'nt focused on that.
i think if you really need this extra performance then latency shouldn't be the problem in most cases
