L4D and L4D2 Lag Spikes Windows 8
Lag spikes in these two games when locally hosting or playing on official servers. New issue, since I upgraded my computer to Windows 8. No lag in other games' multiplayer. What are some things to try? I have a very good connection - A+ on speedtest.com, my ping is always 5, and I give others 20-40. But recently, I've been getting spikes of about 190+, and it really sucks. Any help?
