Windows 8.1 slipping buffers like crazy on screen activity

[yogi_kenobi]

I upgraded my SAC system from XP to Windows 8.1 (wanted the usb 3 support while tracking down to SAW). I've done all the tweaks from SAC manual but I'm getting tons of slipped buffers on certain situation. If I run the SAC and don't twiddle too much on the screen I might get few slipped buffers and all is fine. But if I slap something like Meldaproductions MDynamicEq on a channel and start tweaking it's UI, I'll get few _thousands_ of slipped buffers in no time. This is something that used to work perfectly on XP.

So something is definitely wonky on graphics side, but any ideas how to try troubleshoot/fix this issue?

Start by making sure you're using the latest graphics driver available rather than the win8 included driver.

hy Yogi,

what sound card use your system?

Do I understand correctly?: You're using a computer that had XP on it (probably several years old?) to run Win8.1? What on that computer supports USB3?

Yes, that's it! Win 8.1 installer had installed Nvidias driver which I incorrectly thought was the right one. Downloaded driver from Nvidias site and now SAC is not slipping any buffers. Yay.

I'm using Asus P8P67 PRO B3 rev which has USB3 support on mobo.

Thanks, Yogi (and all). I wonder if that solution would apply also when just using onboard Asus Z87 Plus motherboard graphics out with my LG and Viewsonic monitors?? Or, should I install the graphics stuff from my monitor CDs, or something from the Asus Z87 mobo CD????

(I had let Win8.1 handle it all upon install without even looking to see what was on the Monitor CD or the Mobo CD.... and after doing all the recommended 8.1 tweaks, I still get slipped buffers).

I would always go to the chip maker for the driver where possible. Most motherboard manufacturers don't update the drivers on their website for older boards.

There are a few device makers that don't always give you drivers, such as Broadcom, but most do.

So for your nvidia card, get the drivers from them, same for a Realtek Nic or intel graphics.

All that said if it's for an appliance machine such as a SAC host there's wisdom in sticking with drivers that work so if what came on the install media works nicely, don't update.
