So, earlier on my TF2 decided to change from Dx Level 8 where I got a solid 100fps, to Dx Level 9 where I get a between 10 and 40. I've tried everything I can think of but can't get it to change back, so need your halp

.
My launch options are below and I haven't changed anything in them recently. Also, I'm using Chris Moreframes cfg I think (the one that makes TF2 look a bit like Minecraft).
-dxlevel 80 -sw -w 1920 -h 1200 -console -noborder -nojoy -noipx -novid -noforcemaccel -noforcemparms -noforcemspd
