Re: Cherry removes debounce almost entirely!

That made me cringe. The switches themselves are normal MX series switches, so the bounce time is still up to 5ms at 16in/s activation speed. As for the sampling chip, it's probably not significantly better than other high end keyboard controllers with NKRO, just a question of picking the right debo...

Re: Chief Blur Buster visits AMD's FreeSync room at CES 2015

Oh, and yes -- to be fair -- I am definitely also going to be visiting NVIDIA (likely tomorrow). Keep tuned! Oooh I'd love if you asked a few questions about progress and plans on possible improvements to g-sync: Variable persistence. non-LCD panel technologies And a few possible techniques for wor...

Re: 4K IPS FreeSync monitor by ASUS [ROG PG27AQ]

I think temporal dithering would be cheaper in production. Say you use 10bit PWM and your desired pulse width is 325.7 clocks per 1024. Instead of just rounding to 326, you carry the -.3 to the next pulse, so you get 10bit resolution every 1024 clocks, but 11 bit resolution over 2048 clocks, 12bit ...

LG has a couple 2560x1080 panels coming out with freesync and a max refresh of 75hz.

Re: Blur Busters goes to CES 2015

I'm interested in getting information about AMD's freesync drivers, and the adaptive sync displays(though I'm aware much of this will need to wait until you can sit down and do a full review, unless you find an engineer that can actually talk about stuff): AMD's drivers: Do they use triple buffering...

Re: 4K IPS FreeSync monitor by ASUS [ROG PG27AQ]

My inital guesses about vision response were that photoreceptor stimulation, being based on photons transferring energy to individual pigment molecules and relying on mediated recovery, is probably pseudo-linear until reaching saturation, that recovery is pseudo-exponential, and that longer-term br...

Re: 4K IPS FreeSync monitor by ASUS [ROG PG27AQ]

Yes, the industry needed to be shaken up, but G-sync seems to be dubiously over-engineering approach to the problem. tl;dr: after matching a panel's perceived strobe/dimming levels, controller-created artifacts are easily avoided, and users are left only with determining and configuring their perso...

Re: 4K IPS FreeSync monitor by ASUS [ROG PG27AQ]

I'm not talking about minor tweaks, I'm talking about huge improvements that will require a lot of R&D: Combining variable refresh and low persistence. It's not going to happen if everybody settles on a single standard and tries to compete on price alone. But G-sync doesn't even do that, and nothin...

Re: 4K IPS FreeSync monitor by ASUS [ROG PG27AQ]

Wouldn't it be better to have two competing solutions constantly trying to outperform each other? There is still a lot of room for improvement. No. Adaptive-sync is the simplest possible (and now the standard) communications protocol to achieve the end result of variable refresh rates. FreeSync is ...
