Hm, I must be alone with this issue?

Iv been getting this issue to. Though mostly in the past few days.

nope, i've been getting this too, despite having changed nothing. also getting inexplicable drops in frames during team fights and have never had this before. Gonna try and updating my drivers and see if anything changes

i've read* guides (ex flush steam files)

still happening to me but now rarely

what does the flush do and does it help much?

I used to have this problem when my fps was capped. If you have it capped try uncapping it

[quote=r4pture]I just upgraded to two SSDs, one for Windows and one for Ubuntu. Ever since reinstalling, I've found TF2 seems to freeze for a half a second every once in awhile, usually when I fire my gun or during a battle, or just when turning sharply without much else going on. The frame freezes for a second, then continues as normally. It seems to be getting worse, and I can't seem to figure out why, and it only seems to be TF2 doing it, and on both OSes. Anyone else have this issue, or know of a fix? I've read disabled multicore rendering can help, but its done nothing for me.[/quote]

Reinstalled TF2, and now it is gone for me
