Re: flood's input lag measurements

heh, I'm completely lost now. I'll do some diagrams later and see if that helps me. I'll post them here. I have a feeling I'm just not grasping something obvious. One last question before I try to tackle this with diagrams - is there any significance to separating out CPU vs GPU for understanding t...

Re: flood's input lag measurements

First the CPU works on a frame, then the GPU, then the monitor. Say the CPU is fast enough to finish working on a frame in 5ms, the GPU takes 10ms, and the monitor takes 16.6ms(v-sync on a 60hz monitor). In this case, the GPU finishes the frame 6.6ms before the monitor is ready to display it, so, i...

Re: flood's input lag measurements

yes, 15ms of frame calculation, but if you're gpu limited there's 20ms of input lag(in these 2 steps anyway). An analogy would be a checkout line, where the framerate is the number of customers served in an hour, the calculation time is how long it takes to check out if nobody is in front of you, an...

Re: flood's input lag measurements

oh in that picture the frame rendering time means from the start of cpu processing of input to when the gpu finishes drawing i'm considering the uncapped case, where that time is equal to 1/fps trying to put this all together but am struggling. For now, can you just tell me what gpu limited means? ...

Re: G-Sync and Cloned Displays

Any more updates on streaming while fully utilizing G-Sync? If it's possible, what would be the optimal setup using OBS? If you want to avoid judder on the stream, you should cap your framerate(in game) at a multiple of your stream's framerate. The stream's framerate should either be 30 or 60fps, b...

Re: Lower latency with a PS/2 adapter?

What method did you use to measure input lag? I'm curious about absolute latency too. You made me feel childish and unprofessional :( Well it's true anyway because I didn't use any special tools/hardware. Just my observations I tested in a certain rhythm game where you need to press circles to the ...

Re: Lower latency with a PS/2 adapter?

I own 2 keyboards: one of them is zalman-k500 (red switches) and the other one is a scissor-type slim kb And yes, there is a lower input lag through ps/2 adapter for both of them. Also I think my zalman can have more keypresses at the same time through ps/2 (not N-key roll though) What method did y...

Re: flood's input lag measurements

unfortunately the teensy's arduino mouse thingy acts like it has 500hz polling. Odd, my arduino micro has 1khz polling, and it uses the same MCU as the teensy. You can technically change the polling interval to anything from 1 to 255ms, if you're willing to look up the USB configuration registers, ...

Re: CS:GO -- Does 2 milliseconds matter?

I think if 2 milliseconds really matter, then only in a perfect LAN-Enviroment. It isn't a question of whether 2 milliseconds matter, it's how often they matter, because latency is cumulative. Any time you have a race, there's a chance the 2ms difference pushes you over the threshold, but it does h...
