275.33 is what I use. I only have a few older choices back to 266.66, the first to support my video card, and anything newer than 275.33 crashes.

Downgrade to 267.59 IMO (will need to modify INF). That was my driver of choice for mouse response / lack of bugs or flash crashes / etc on 570gtx. I've tested every Fermi driver on my 570gtx and the only ones that aren't garbage for one reason or another are:

263.09
266.35
267.59
290.53

I would probably still be using 267.59 but 290.53 lets me force 70hz on my 1080p Samsung P2770H, older drivers don't.

I told you man. It's so easy to notice a large increase in mouse responsiveness by changing scaling to "Display - No Scaling". If someone can't notice anything by changing this, they either have completely horrible reflexes or their system/monitor isn't affected by this setting somehow.

That backed up by fact / happen on every board? tongue.gif

This is a real issue.
Try to bump the thread on Nvidia forums and let the reps on Twitter know, and hope they'll listen.

There are some giant posts about it on places like Guru3d. It's really idiotic that Asus doesn't put the HPET option in their BIOS.

About the lowest DPC latency you can get with HPET on is 30 or so, with it turned off, it can go down to like 5.

If you use an Asus board and want to see what it feels like with HPET off, you can probably load up TimerResolution.exe and watch your DPC plummet and mouse response increase: http://www.lucashale.com/timer-resolution/

This is kind of a side issue with Asus boards in addition to the whole Nvidia scaling & driver lag thing.

I find it hilarious that the timer program just bumps my DPC from 30-120 to 500+ :]

have you guys tried setting per-rendered frames to 1 or 0 to see a difference?
and try setting windows to best performance for the sake of testing it out

It's a buggy ass program (at least the free 1.2 one) and will go to 500 when it bugs out. I think it's some kind of conflict with DPC latency measuring programs. I forget if you're supposed to launch TimerResolution.exe first or your DPC latency measuring program first, but if you do it wrong, it bugs out and goes to 500. I think even minimizing the program screws it up.

My system (Asus Sabertooth 55i) goes from 30 DPC latency to 5-9 when I tested it.

Whatever settings someone uses for pre-render doesn't really matter since it's a static variable and isn't related to anything else that's been said in this thread. But yea, these are the settings that I've found to be most optimal:

Are you using http://www.thesycon.de/deu/latency_check.shtml

Or something else?

I also had it bug out to 500ms when I tried it, but it worked fine when I did it a specific way.
