I'm running a 3570K, 1060/3GB, 16GB RAM, so your rig's better in every way, here's the settings I run to get tolerable frame rates with the eye candy I care about unless there's a big crowd, still hunting for a decent tuning for that and dreading horde night but short of multiple zeds going live at once I've seen anywhere from 20-65 FPS, generally about 40.I'm running a pretty high end system. 3700X, 32GB RAM, 1660Ti. My FPS drop seems linked directly to texture quality. Quarter quality = 50-60FPS. Anything over that, single digits unless I stare straight at the ground. I'm gonna go out on a limb and say the browser has nothing to do with the overall problem.
