Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

Thanks for the review Jorimt. Agree on the point that the caps-lock-light method was not evaluated; it would surprise me if it really was much different than connecting an LED to a mouse button though. Obviously the 240 fps phone camera does a less precise measurement than a 1000 fps camera. My form...

Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

I did some end-to-testing with Apex Legends yesterday; outcomes are: - NULL, NVIDIA limiter, and RTSS perform on par with each other: they reduce latency with very similar amounts. When I say NVIDIA limiter I basically mean NULL enabled and a specific limit set in Profile Inspector, ie 97 fps in the...

Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

Jorimt, you are right, these new options require new rounds of end-to-end testing. Although I am fairly confident that PresentMon includes the relevant sources of latency to measure influence of frame rate limiting, sync, render queuing. It does not record latency coming from USB devices, monitors, ...

Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

Since the addition of the NULL, the Nvidia driver frame rate limiter appears also low latency. The driver api documentation** since then has a new field as well, PS_FRAMERATE_LIMITER_LOW_LATENCY_AUTO , which replaces a flag that Nvidia profile inspector already set by default. If you set the frame r...

Re: PG 348Q / top screen flickers

Same screen here. Also this issue, but seldom during very low fps situations outside of gsync range. I once read a post by Chief here that explained the issue occurs due to brightness differences or such, I cannot reproduce. I would not invest any time trying to fix.

Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

Tested some Vulkan games, e.g. Doom 2016, with VSYNC On (in-game off), NULL Ultra. There it does not seem to work and the game FPS hits the monitor refresh rate just like before, resulting in ~1 FPS of queuing latency.

Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

Another observation: since the NVIDIA Ultra Low Latency (NULL) feature was added, the FPS limiter in NVIDIA's driver, set through NVIDIA Profile Inspector, is also low latency, that is, sub-frametime latencies measured by PresentMon, similar to RTSS. You only set the FPS limit and let the "Frame Rat...

Re: Driver 441.08: Ultra-Low Latency Now with G-SYNC Support

In some testing I did it seems that putting NULL to "Ultra" and Vsync to "On" automatically caps games to below the refresh rate of the monitor (97.3 FPS @ 100Hz gsync screen). With some monitoring using PresentMon, it also seems to have the same latency characteristics as previously capping to 97 F...

Re: Extreme stutter and framedrops with multi-monitors on wi

Longshot: for me a cause of microstutter (in games) is having the Balanced or Power Saving power profiles enabled. Did you rule that out by forcing Prefer High Performance?
