USB polling precision - Page 18

post #171 of 769
Thread Starter 
Overkill for your desktop experience - definitely. But like I say somewhere in the OP, when you run a game things get busier and any improvement that may have appeared negligible in idle can potentially be noticeable there.

hm yea that's definitely a possibility. maybe that's related to the m_rawinput 1 paranoia

After more testing with HPET on + MSI mode versus HPET off + legacy IRQ, I found I preferred the latter in terms of mouse movement and more stable FPS.


How about disabling not used PCI lanes?

Could improve anything

Can someone hit me me up with a TLDR summary I'm at work and I can't read this for 3 more hours

I disable several things in device manager. Also my IRQ looks slightly different now because I leave the Intel network adapter and SATA ACHI controller in MSI-mode (how they defaulted from install). Here's both: http://i.imgur.com/him1DaA.png

Edit: now I have my GPU, PCI Express Root Ports, Intel MEI, and PCI bridge in MSI-mode as well. Previously I got weird lag spikes/stutters with GPU in MSI-mode but it's behaving well now. My FPS in test demos and benchmarks went up ~2-3% in CS:GO from these changes. And USB polling precision has improved slightly, mainly that the spikes are fewer and smaller.

So when you say legacy IRQ, does this mean it isn't handled virtually by the Windows ACPI?
post #178 of 769
Not sure what you mean. MSI-mode are the ones with negative numbers in the parentheses (Intel Network Connection and SATA ACHI Controller) and the legacy IRQ channels are non-negative (GTX 680, Xonar DG, etc.)

Read around about IRQs and found this

So I just thought you turned off ACPI in Windows
