Software Can't force antialiasing

[danep]

Aliasing is especially pronounced on runways, objects (the ISS), and the virtual cockpit, so I'd like to apply full-screen AA somehow. I know it's not a built-in option, so I tried to force 4x AA using ATI Tray Tools (for Direct3d applications) and ATI Catalyst Control Center, but they don't seem to affect all features - the ISS looks MUCH better I think, but runway stripes still look pretty jagged. Any idea why this would be?

Runway stripes aren't realized on meshes, but on bitmaps, and that's why antialiasing doesn't apply to them. They are only processed by a scaling filter, and eventually by using mipmaps, and antialiasing is used only for edges of meshes (but transparency multisampling might be used for edges of a transparent region of a texture).

Forcing AA in the driver is also known to cause some issues with Orbiter, such as the HUD disappearing and visual helpers not working.

Thanks for the replies, that makes a lot of sense- I guess I should have realized that the runway was just a bitmap!

Haven't had any issues with AA yet, but I'll keep that in mind.

Im running a NVIDIA 9800GT with 1 GB of ram and i run Orbiter2010 full screen with AA enabled at x4. The resolution I use is 1920x1080 I use NVIdia's control panel to force this. The sim looks wonderful and runs at around 45 fps nearly all the time. The only issue i have is every once in awhile Ill get the whole screen flash all white for maybe a frame and then everything returns to normal. This happens also when AA is disabled so im thinking it is more the driver having a cough. The only other thing is if for some reason i hit windows key and go to desktop, then return to the sim, i have to do some "window and Panel" refreshing. Other than that it is all good

This may be a stupid question, but did you try checking "disable hardware pageflip" to get rid of the white flash?

And yeah, I've wished for this feature before, I really want to try it now!

lol is that what that is for??? i had no clue, let me go try that

and yes the diable pageflip flag fixed that issue. Ty for that.

In addition to disabling hardware page flip, Doug's vista boost addressed the white flashing issue I believe and it should also improve your frame rate.

Yep, i have VistaBoost working. Another good way to get framerate is disable the smoke/exhaust effects. I can prob gain 10 fps easy when i have those disabled.
