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.Edited by VolsAndJezuz - 2/4/16 at 11:35pm
