Are you positive it is an FPS drop or is it potentially network stuttering?

my game is still stuttering like this, please help. I've even tried reinstalling the game. also i doubt its a network stutter because it doesnt happen in any other game even source games.

had this same issue for a long time, only thing that fixed it for me was closing steam client bootstrapper through task manager. this would fix it for like an hour, then id have to close it again.

i think i might have fixed it, there was this windows setting called Game Mode that was on so i turned it off

edit: yeah thats what the problem was
edit2: thats NOT what the problem was

yeah actually this is still happening and ive additionally tried completely reinstalling tf2, changing dxlevel, overclocking my cpu, disabling windows aero effects, uncapping and capping my max fps, changing to a different graphics config, updating windows and disabling amd lag compensators. None of that worked, my game also stutters whenever someone joins a team too.

have you tried disabling steam overlay for tf2 ? I used to have some stutters because of it a while ago

my bad I read too fast sorry

We may not be having the exact same issue, as I don't remember my game doing it when someone joins a team. But sometimes I will find my CPU usage spiking to ~90%+ every minute or two which causes pretty bad stutters (i7 9700k). Typically happens if I have too many chrome tabs open. Sometimes it's fine, other times it does this frequently. If I just close out all of the chrome tabs I'm normally good to go. I will also get stutters if the Discord overlay pops up a message while I'm in game.

Probably not all that helpful, but figured I'd share my similar experience.

I had a similar problem when I reinstalled a few weeks ago. I noticed that it only happened when I had discord open, and I (hopefully) fixed it by disabling discord's hardware acceleration:

I had this issue for YEARS, are you sure that you installed TF2 on the same hard drive as before? what made it stutter so much for me was that I had it installed on an extremely slow hard drive, once I put it on an ssd it was all gone

this is already off

ive tried installing tf2 on both my ssds

ive also tried closing all browser tabs

Check in task manager for a thing called "Steam WebClientHelper" and try to force quit it. Sometimes "SteamWebClientHelper" takes up like 3 GB of my RAM, making my game stutter.

just launch steam with -no-browser, dont bother with killing processes

how

add it after location path in your steam's shortcut icon

i had this problem for years until i disabled the webhelper thing with -no-browser in target location in steam properties

these helped me massively,

if someone can help me but needs additional diagnostics just tell me and ill give them to you

I had some similar issues a while ago.

I know you mentioned "changing graphics config", already but that's what worked for me. I updated to the most recent mastercomfig at the time of the thread, I still had the issues for a while and then they just mysteriously disappeared. Maybe instead of changing graphics config just use the latest version of mastercomfig? Idk it's probably worth trying if you haven't.

EDIT: Also, maybe it's worth double checking if your .cfg files have any weird commands in them

ive even tried replacing my ram and reinstalling windows, didnt work.

edit: i played mge with only a few people in the server for about an hour and didnt stutter at all
