Re: flood's input lag measurements

Thanks again. Very comprehensive. Wasn't sure if it did decimals, so I threw in 84 as well(turns out it does do decimals) The engine just looks at fps_max X in a 1000/X manner and so can adjust interval timings regardless of there always being a discrete amount of possible frames in a second. I'm ve...

Re: flood's input lag measurements

Why would you expect them to ramp up? With fixed delay + 1ms random delay cascading around the frame intervals seems logical. Thanks for all the measurements so far, my test setup is coming along as well. In the mean time, can you test triple vsync 85hz vs. triple vsync 85hz fps_max 84.9 with the up...

Re: flood's input lag measurements

I always felt that capping framerate below refresh rate decreases vsync-induced lag, but your results are right that at least 1 up to a few frames per second will be displayed twice as they miss the sync because of fluctuation/frametime variance. I think you should go away from external limiters tho...

Re: flood's input lag measurements

The following options are all pretty much identical, which is either ~22ms or ~34ms, depending on whether this frame happens to miss the v-sync deadline: DFC 85 with v-sync on DFC 84 with v-sync on "Lock frame rate up to monitor's refresh rate" with v-sync off Are you suggesting these are identical...

Re: flood's input lag measurements

He doesn't want to know all of his work is for nothing, I kinda feel sad for him sometimes. :( I try to not be pitiful in general, but yeah the picture of r0ach's world slowly crumbling as he fails to successfully blind test his claims over and over is both funny and sad. I don't think his way of t...

Re: flood's input lag measurements

Would admittedly be quite hilarious if you started supporting his claims, cooking up some measurements and all and letting that explode in his face after the period where OCN loses its mind and he spends hours shitting on everybody. Seriously though, sometimes I get the sense he has some kind of men...

Re: flood's input lag measurements

It's mostly annoying how discussions never lead to anything. Sure, we could all take the stance where ultimately it doesn't really matter and be satisfied with what we do have, but if you look at people like John Carmack, some of the most knowledgeable and experienced people in these regards also ar...

Re: flood's input lag measurements

That's persistence. Ignoring phosphor persistence, we stop noticing non-illuminated phases at about 80Hz, i. e. 12.5ms.

Re: flood's input lag measurements

An alternative possibility is that external limiters simply delay the buffer swap to maintain the interval (effectively limiting framerate because the back buffer is occupied, so map load times/server frame times would be prolonged there as well). Swap buffers A lot of time in Swap Buffers is usuall...

Re: flood's input lag measurements

Something to go along with that: With external frame capping (Inspector), +showbudget shows that Mat_ThreadedEndFrame (basically time it took to finish the frame after initializing the render) is the main framerate decider, and it's going back and forth constantly (random points of waits). With the ...
