I've been using SweetFX now (with max SMAA) for a little while and it makes a decent difference. I think it makes more of a difference than 16xQ CSAA, 16x CSAA or 32x in the Nvidia control panel ever has. I think the FXAA settings in the Nvidia control panel do a little bit, but not much.
The thing is, all AA things seem to work ok for most external views of the aircraft - but the cockpits all still look like terrible jagged messes. The gauges all shimmer constantly, the jagged edges of the gunsight glass and metal parts are very noticeable. However, the worst thing is when I'm in a 109 and the cockpit frame directly in front of me is a huge pile of jaggies. No amount of AA seems to tame it if it has light reflecting off the edge (which seems to be almost always).
I've learnt to look past it for now, but I was hoping there was a way to get the Nvidia options working properly. Right now, it feels like they work as much as 2x AA does, no matter what setting I use. My computer seems to run CoD fine, so I would really like to be able to properly up the AA to 16x or 32x, but it doesn't seem any different than 2x.
Did the FXAA get rid of all of the jaggies for you, or just most of them? If you're in a 109, are the main front cockpit frame parts edged with big jaggies? If not, what settings are you using? I'd really like to try them out if they can make the front part of the frame relatively smooth (or even jagged, but not glittering and moving!).
Thanks
Edit: Oh, I just realised what you meant by "global". Awesome, I haven't tried that yet. I'll give it a go later on (not at my main computer right now) and see how it goes. Thanks very much!
