TF2 AA problem with ATI HD4870 1GB

[AtlanticP]

Hey Guys,

Upgraded my graphics card today from an Nvidia Geforce 8800GTX 768MB to an ATI Radeon HD4870 1GB. Runs beautifully in max settings in TF2, Currently between 160-200 fps (regardless of map ) but when I quit the game and go back in its turned off the MSAA which I had set to 8X (The Max it would allow in TF2) Antistropic Filtering remains at 16X which is fine but I cant get it to hold the Anti-Aliasing. I have an autoexec.cfg file for a couple of other settings but I dont know what I need to add to this in order to get the AA back to 8X instead of not enabled.

Main System Spec:
Intel Q6600 @ 3.0ghz
Abit IP35 Pro MoBo
4GB OCZ Reaper
ATI Radeon HD4870 1GB

Does anyone have any idea's as it looks pants with the AA off


Thanks In Advance,

Chris

i had that problem everytime i minimize or restart the game aa would switch of.

i think it i did go to my steamgames> press mouse 2 on tf2 > propertys > set launch options and delete the thing in it. had to do it couple of times till it fixed it self i think.

Excellent Mate, that worked and has held the AAX8 setting. Didn't even realise that line was in the launch options lol

Thanks Again Mate
