Re: New low latency nvidia drivers

Eh, I wouldn't call it a collaboration on Tearline Jedi. I still haven't helped Mark with Tearline Jedi so I don't deserve any credit for it. But he has been very helpful for my application. Without his crucial suggestion to wake up the GPU prematurely, I would be greatly annoyed by GPU power manage...

Re: New low latency nvidia drivers

I forgot to mention: the 40 tearline Balanced-battery standard deviation is not because the algorithm doesn't know the exact vsync period and phase. It still knows them exactly to 1 tearline. Rather, it has significant trouble trying to swap the framebuffer at the right time. It spinwaits on the tim...

Re: New low latency nvidia drivers

Amazing! Just out of curiosity what is the time that the prediction took to run and which frequency it is updated? You said "from the past frametimes..." but it seems very uncertain by nature to have only 1 line of deviation if your observable are just the past frametimes. Even for good performers ...

Re: New low latency nvidia drivers

@ad8e That sounds great! Are you around Santa Clara /Bay Area by a chance? We are looking for good people to join our (AMD) driver team... Sorry, I'm in New York, and I am not able to switch jobs until around next year July. Also, I'm unqualified to work on a GPU driver team, because my experience ...

Re: New low latency nvidia drivers

Their "just in time" technique sounds exactly like what my own vsync algo was doing. Really good for them. I had to do a lot of sophisticated math for frame estimation and sync timing which I doubt they did at all (so their algorithm will probably suck). But having a bad just in time technique is st...

Re: Wooting One keyboard tested against Logitech G Pro Keybo

How do you know they are lying? Do you think it’s likely that the apex pro and b975 (and their tkl version b930) will outperform the gpro? We know they're lying because there's a minimum latency of 0.5 ms caused by the USB polling, which can be taken downwards using sketchy techniques but still won...

Re: Wooting One keyboard tested against Logitech G Pro Keybo

I changed my mind about the Wooting One. I was noticing some issues, so I benchmarked it to get data. The Wooting One's electronics are not good. My Logitech G-Pro's electronics are better, although its binding wobble is still a major physical problem. Data: https://pastebin.com/qxVpgm9W Test method...

Re: Wooting One keyboard tested against Logitech G Pro Keybo

The Hall Effect keys in the Apex Pro should theoretically be better than Flaretech switches, and Wooting is exploring the same style (Lekker keys, to be released in 2020 or maybe never). Even then, their Lekker keyboard is planned in full size, and I don't want to make space for a full size keyboard...

Re: spacediver and ad8e public collaboration [reaction resea

Maybe it'll be easier if I build it, and I already own the necessary mouse. I think in two weeks I might have some time.

Re: spacediver and ad8e public collaboration [reaction resea

I've spent too much time today trying to overclock my other mouse (the one with higher cpi) to 1000 hz, as it's currently stuck on 125hz. No success. I can pick up this mouse for about $15 down the street: https://www.redragonzone.com/products/redragon-m601-centrophorus-3200-dpi-gaming-mouse That m...
