My friend has been having some trouble with TF2 and CSGO having low fps (and sometimes crashing) on a computer perfectly capable of running both games. He gets around 30-40. We fixed TF2 crashing by setting it to window borderless. He can run For Honor and Rainbow Six Siege just fine. Those games take a lot more power to run, but for some reason TF2 and CSGO run poorly for him. Any suggestions?
