When I alt-tab in out of TF2 and then back in, TF2 freezes. I didn’t have this problem before. Help ?

are you using windowed mode? If not I would recommend it.

remove -dxlevel from launchoptions! it even says it in the description

If removing dxlevel doesn’t help, add -sw and -noborder to launch options.

fyi I removed it but I run it in fullscreen

There’s your problem then.

You need to run borderless fullscreen for lagless alt-tabbing. Like other ppl have already said.

-noborder into launch-options.

i run 800×600 and i dont freeze in fullscreen, so that isn’t the problem

it isnt the problem and fullscreen is also much smoother.. i dunno why would someone want windowed other than beeing able to put windows on top of tf2 bcs even fullscreen alt tab is like 0.5 sec

I put -sw and -noborder and changed resolution to 19000 x 600. Changed also launch options’ resolution to be correct. Now I run in borderless windowed fullscreen or smth.

TL:DR: FIXED

That’s a badass resolution.
