Make sure your 3d resolution is set to the same as your interface resolution.
Disable Post-Processing effects. Makes it look like arse.
Put shadow detail to High/Very High as this makes the gpu do the crunching instead of the CPU. Same for Video Memory.
Set HDR to normal too.
Download this beta patch if you want to play on our Wasteland server.
If you want help with Wasteland, join TS in the first post and we can help you out! You will also need ACR Lite which is available for free - http://www.arma2.com/index.php?option=com_rokdownloads&view=file&Itemid=20&id=805
Yeah I already done the beta patch and installed ACR Lite and joined the server last night, and I think I've changed most of those settings bar the shadow detail but it still felt a little jerky in places.
I'll jump on TS on tonight maybe, if not then tomorrow hopefully.
Set video memory to default,it then uses the full amount on your card.
The very high setting only uses 512 of vram.
Will do cheers.
