Re: Display frametime vs input latency.

With v-sync off you shouldn't be getting any input latency due to refresh rate, because you're not waiting for the next refresh to display the new frame. You will get latency due to framerate though. 240hz camera is also a little slow for this. 8 to 14ms is pretty good if we're talking about an actu...

Re: Display frametime vs input latency.

Depends on what you're measuring, because the whole screen doesn't update at the same instant. V-sync on vs off, or a single point on the screen vs anywhere on the screen. You won't see that 4.16ms if you're talking about vsync off and are looking for a change anywhere on the screen. You will see it...

Re: CRT's Refresh Rate

Not sure what you mean by "real". Yes, CRTs can have high refresh rates, it comes with reduced resolution. Whether this tradeoff is worth it or not depends on you. Most people with CRTs use neither the highest supported resolution nor the highest supported refresh rate, but choose something in betw...

Re: Arduino Input Lag Tester for Dummies?

I wrote up my version of it here: https://forums.blurbusters.com/viewtopic.php?f=10&t=3005&p=22634#p22634 Though the code will only work for the boards with native USB, like the micro or leonardo. I don't think the mega can enumerate as a mouse. You can replace R1 and R3 with a phototransistor and a...

Re: Is this placebo?

In theory, it shouldn't matter, but that 30fps cap might not actually be exactly 30fps, so you can get the 33ms of animation happening in 16.7ms of on-monitor time, and then the next frame you have 33ms of animation happening in 50ms. That's assuming v-sync on. With v-sync off, it gets more complica...

Re: Isn't it better to disable gsync and increase FPS limit?

Latency is cumulative. The difference in pixel transition time is added on to everything else, so you can't really make up for it by increasing framerate. Increasing framerate will have the same impact regardless of panel type. As for whether it's better or not, that's debatable, because you'll be g...

Re: Night/Day

Network lag can be time dependent, due to network load. Though that shouldn't change how the mouse behaves.

Re: Night/Day

Unless the temperature in your room changes enough to cause throttling, I don't see it having an impact.

Re: Cap your fps people (battlenonsense)

It is possible in the driver, and most likely third-party software. For example, can limit cpu to make the video card wait for the processor. The question is different. When to stop? 1 frame delay, 234? or in milliseconds? Waiting for 1 frame at 240hz is not the same as waiting for 1 frame at 60hz....
