Apologies in advance if I mess up writing this post in some way.
Recently I've gotten a new CPU (AMD Athlon X2 6000+ 3.1Ghz) just to try to get some more frames for TF2. I installed it and it seemed like there weren't any problems, but in TF2 and only in TF2 every maybe 20 seconds in of playing even on an offline map such as cp_badlands I get frequent stutters that affect my fps and ping. I'd be very grateful if someone could help me.
I've already contacted my ISP about getting my modem replaced as I thought that was my problem but I'm still hoping it's something else because before the new CPU I was not getting this problem.
