Re: Measuring keyboard input lag

Someone at https://www.reddit.com/r/thinkpad/comments/9ivh0u/thinkpad_keyboards_measurement_of_polling_lag_and/e6n9dc3/ reported that pressing two keys simultaneously on the MasterKeys Pro S, a 1000Hz keyboard, makes one of the two keys appear first every time. That sounds like either the firmware ...

Re: Blur Buster's G-SYNC 101 Series Discussion

In the article it says ingame limiters should'nt introduce any latency. I've been messing around with my Destiny 2 settings and having the limiter on introduces very noticable input lag, basically like Vsync on with floaty mouse. I turned it off and instantly its super snappy. Is this just the game...

Re: Newly calibrated CPD-G520 lag in WoW, not in CSGO

Csgo is flowing nice, no stutter but only 85 Hz even on 800x600. Well, that would be because 85hz is the highest refresh that monitor supports, at least without a custom resolution. The lag is definitely coming from the PC. As I disconnected my CRT and plugged the LCD back in and started WoW, the e...

Re: Lag testing for 4K Displays

The high speed video method is a good starting point if you already have a camera capable of ~1k fps, but it's also incredibly tedious if you want any kind of accuracy. Basically you modify a mouse to light up a LED when you click, and count the number of video frames between the LED lighting up and...

Re: Fast sync+ lightboost with uncapped fps

It's ok, but with fast sync you generally want to cap framerate at the highest sustainable multiple of refresh rate.

Re: Explain this Vsync behavior please

If a single full back buffer prevents the GPU from working, it's double buffered and v-sync will halve framerate. If it doesn't, it's triple buffering, and won't halve framerate. The main important distinction between different triple buffering implementations is those that drop frames(this causes ...

Re: Explain this Vsync behavior please

As for why the game isn't dropping to 30fps when you crank up the settings, it probably isn't honoring the double buffered vsync setting for some reason. Actually I suspect a different reason for that. It's probably because of the asynchronous frame presentation in modern systems. Even when the fra...

Re: Explain this Vsync behavior please

But 58/59 cap will cause 2/1 frames (increase frametime) to get dropped and should trigger Vsync, no? What's the difference between RTSS forcing CPU wait, and a real GPU fps drop to 59? In the context of double buffered v-sync, there are two framebuffers, one which the GPU can render into, the othe...

Re: Hidden settings in Nvidia Inspector that reduce lag

It's likely still better to just use a framerate cap to avoid hitting the max refresh rate.

Re: SLI input lag questions

I believe most SLI implementations have more lag than a single card at the same graphics settings, though the variance may be lower. The few games that use split frame rendering might have less lag than single card, but SFR doesn't scale as well in terms of framerate, so you don't see it as often. I...
