Edit: I solved this. I forgot I can set per-application power profiles in NV Control Panel to "Prefer Maximum Performance" which does what I need as described below. Heh, I used to "know" this but must have forgotten. Ultimately I feel NV needs a more aggressive clock ramping setting instead of just all or nothing, or there is some bug in detecting when to stop upclocking that is too conservative.
TL;DR - How do I force the gpu core speed to ramp up higher at partial load (ideally) or if necessary run at full speed on 2D/desktop uses?
I've a PNY GTX 750TI (std 1020MHz Core/1350MHz Mem) that I need more shader performance from during video playback, and I understand shader clock is tied to core clock, so...
I notice during video playback, in GPU-Z, it starts at 135MHz core, ramps to 180MHz, then 203-ish MHz, then 231MHz as the core % utilization rises above ~80%.
Problem is, it goes no higher than 230MHz and still drops frames. This is not a CPU or other bottleneck, please stay on topic!! It is shader features in the video software that bog it down as they are enabled, and disabling clearly shows lower GPU load, it even downclocks yet video frames no longer drop.
I want to force it to run at higher than 230MHz during the video playback, ideally to set it to ramp up to a higher speed based on % utilization, whichever. I don't think I really need it at 100% full speed, just faster than 230MHz.
I'd prefer a software solution but am not opposed to bios editing to accomplish this, but I don't know what I am doing with the bios editing, have only done myself, and seen guides on how to do overclocking while I only wish to increase the clock rate ramping up higher in the scenario above, do not need a higher overclock max speed. Little bit higher core from o'c wouldn't even do any good if it's not ramping that speed during use.
