Anti Aliasing with 250 gts in 1946
 

Hi, I've gotten back into IL-2 and for some reason my anti aliasing has stopped working. I figured it was possibly due to driver issues. However, I have tried reinstalling the 301.42 drivers as well as using older drivers that I know the AA worked with and still nothing. I have also tried using nvidia inspector to force AA on. I have reinstalled IL-2 and tried it both patched and un-patched.

I have noticed however, that if I switch from OpenGL to DirectX the anti aliasing works fine. I have no clue why this is happening, I'm pulling my hair out! Any ideas?

Oh and I'm running xp-32 bit and an nvidia 250 gts.

Using the program specific settings or global settings? I always used program specific..and still do. Also override the antialiasing rather than enhance... not sure if it makes a difference but I always do that.

I used to have a 250 GTS.. it can do it for sure. Maybe some newer driver is a problem.

Thanks for the help, but I have always used program specific settings and override. It used to work lol. I stopped playing for a year or so then I come back and it doesn't work anymore. I tried the 186.18 driver and it didn't work either, and I know it used to. Maybe there is something on my computer that is interfering with it.

I did set up freetrack on my computer in that period. I know that some people have had problems with anti aliasing and trackir, maybe the same problem is happening with freetrack?

Edit: I had pacific fighters laying around (came in a bundle with IL-2 and Lomac) so I installed it and AA didn't work in it either under opengl. I wonder if its an opengl related problem... I'm installing the x-plane demo to test if anti-aliasing works in it. Gonna be about an hour and a half before its done though.

I'm still on old drivers but what about FXAA everybody was talking about?

plus what do you mean by "I tried the 186.18 driver"?

I tried fxaa and no luck. What I meant by "I tried the 186.18 driver" was that I rolled all the way back to that driver. I've tried other nvidia driver releases also. None of them seem to work.

I tried the X-Plane 10 demo (which is opengl) and forcing antialiasing didn't work in it either. It seems that my computer doesn't want to use aa in opengl.

Try this conf.ini

Please not that you can use water = 1/2/3/4 with Nvidia

Thanks, but it didn't work.

Could be some deeper issue. Sounds like a pain but remove TrackIR, Freetrack, whatever else you feel might interfere with the game.

Uninstall all of the nVidia drivers and then run some sort of driver sweeper... I used to use this one: http://www.guru3d.com/category/driversweeper/

Once you're free of all of this stuff get the latest nVidia drivers from their website and install those. See what happens. If you still aren't getting AA in OpenGL applications I'm not sure... but that speaks to some sort of deeper OS issue. It's very likely not a hardware problem...

Alright, thanks for your help but I couldn't get it working. I've decided just to reinstall xp on my smaller drive and put Mint 13 on my bigger drive. All I need xp for is my flight sims... Anyways, thanks again everyone for your help.
