Option for optimized GPU mode to keep using dGPU on battery if apps are using it

Option for optimized GPU mode to keep using dGPU on battery if apps are using it

@IcePanther hello,

This is already the case.

Application already checks if GPU is being (actively) used before automatically disabling it. In case of that - it shows popup as well

g-helper/app/Gpu/GPUModeControl.cs

Line 229 in ff92229

if (HardwareControl.IsUsedGPU())

Current threshold is 10% GPU Usage

Thanks

Hi, thanks for your quick answer.

However, this only works if the GPU is under load, not used by an application.
If, for instance, you're in the menu of a paused game (some do interrupt rendering when you do), or in this case, the LLM instance was between generations, so it didn't load the GPU at that precise moment, but VRAM was still used by it, and when I tried to resume activity, it crashed.

Is there a way to detect if there are active handles pointing to the GPU instead of just the GPU load ? Or if it's simpler, maybe also detect if the dGPU's VRAM is being used ?

@IcePanther there is no way to detect is GPU is used but not used at the same time reliably.

Nvidia / AMD driver can report list of applications that "use" GPU atm - but it will almost always include harmless things like browsers, windows components, etc. Preventing dGPU swtich based on this list will stop this feature from working at all (what pretty much happens with AC all the time).

If you have some non-trivial usage for your GPU like running ML on it, i would just advice to stick to Standard mode.
