Not without adding latency. At 20fps, 1 frame of latency is 50ms, not a good tradeoff.

Re: Game locked at 20fps, what RTSS settings?

If the game is locked at 20fps, basically nothing you do will improve latency. The point of the adding a cap is to keep framerate under refresh rate(thus reducing buffering throughout the render pipeline), but you're already 40fps below your refresh rate, so it's not helping anything.

Re: Download -> NEW FPS Limiter for Vulkan, OpenGL, DirectX

So basically there isn´t a single frame rate limter that doesn´t add input lag? That´s a shame.. None of the frame limiters add any input lag. In fact, they reduce input lag. The only exception is the NVidia limiter, which doesn't have a latency benefit. You seem to be confusing the fact that the e...

Re: About triple buffering

Off. All the problems that triple buffering solves are already fixed by g-sync. It would only come into play in some weird edge cases(dramatic changes in framerate), and to no benefit.

Re: Measuring keyboard input lag

For mouse button latency, I agree with you. The lowest-latency mice buttons are probably at that level of 0-2ms. Building a good switch requires good electronics, tactility, and durability. Switches are usually outsourced to Huano/Omron for tactility. Omron switches often have double-click issues, ...

Re: Measuring keyboard input lag

The three approaches I think are best all have in common a test platform capable of both GPIO and USBHost. The easy way I can think of is to slam the mouse button into a keyboard button at high speed. This causes some delay from physical key pressing speed, which is acceptable because humans have d...

Re: Only g-sync or with v-sync?

Leaving v-sync on will prevent tearing when the framerate recovers from a stutter, when the single frame interval is faster than the refresh interval. This will have a small latency penalty, but only for the frames that arrive early and would have resulted in tearing. The median latency shouldn't ch...

Re: Adaptive vsync vs Regular vsync Nvidia driver

I also feel that "Adaptive VSYNC" has smaller input lag that regular VSYNC. I think that it is using double buffered VSYNC and thus has lower input lag versus the classic VSYNC which usyes 3 buffers. Are there any input lag tests for this? Normal v-sync is double buffered, and has the same input la...
