(bumped) Issue Report: [TF2] Sudden FPS drop, only fixable by completely restarting the game.
I have reported this one for the first time over a week ago but it didn't get a very big response, much less an official response, yet it continues to make the game practically unplayable for me to this day (unless I play on another map but dustbowl :).this is my original post
with a longer description, but I'll summarize it again:
On most maps, after a while (or instantly on join), TF2 suddenly drops framerate from a smooth 150 - 200 to unplayable 15 - 30. I say most maps because it virtually never happens on cp_dustbowl (only once in 2 weeks) yet almost immediately or within an hour on any other map I tried. The only fix that works for me is to completely exit out of the program and restart it.
Since my first report, there were some updates to Steam itself and I believe also one to TF2, but the problem remains.
Except for Steam, nothing changed on my end, but I'll repost my sysinfo for the sake of completeness:
