The mobile app randomly recommended me a post from u/no6969el with this tool that stops windows processes from stopping up the system. I didn't think it would do much because I already have a decent CPU and a pcie 4.0 x4 SSD. Whatever it did actually improved 1% lows consistently across the board and the input for counter-strafing is a lot more accurate and less frustrating. Even bunnyhopping feels noticebly smoother and I can casually chain 4-6 hops on official servers using scrollwheel without capping my fps at all (aside from freesync.) Your mileage may vary, but if your pc already runs circles about the min specs and still feels laggy, this is worth a shot because I was thinking about selling my CPU and getting an X3D one for better 1% lows before this. I'll explain more in comments, but I'm starting to think maybe it was just the timing and it really was Windows 11 and not the upgrade to Source 2 lmao
