Fullscreen/AA doesn't always work

[Arc †]

My video settings are selected to fullscreen and AA is turned on, yet half the time AA is not turned on and I have to alt + tab to go fullscreen. Anyone know why this is? Even when the boxes are checked, the AA is not on.

Your situation is kind of unclear.

AA = anti-aliasing? (just to make sure)

If you have set your game to run in full-screen, it should be allways in full screen. Or are you running in 'borderless window' fullscreen mode?

AntiAliasing should work in both windowed and full screen. And your ALT-TAB doesn't really make sense to me.

Check the resolution when you have AA problems, it more sounds like a scaling problem in borderless full-screen.

You can also enforce AA in your GPU settings. You can try that and see if that works for you.

Thanks, Yes AntiAliasing. It's very bizarre. Last night it returned to working (lots of jagged lines, then a restart cured that problem) and then this morning it's not working yet again even after a client restart and checking the video settings.

Alt-tab puts the window into fullscreen, even though it is checked as fullscreen (not windowed or borderless which I also tried)

Open the game in a testdrive:
- Don't use ALT TAB, use ALT-ENTER to make it full screen
- Then quit the session, close the sim.
- Then try starting it again and see if it opens full screen right-away.

Yes sorry alt + enter is what I use. I have quit the session, closed the app, restarted from steam and my problem continues to occur intermittently. Even between practice to the race sometimes it will enter into the windowed mode.

In your MyDocuments\iRacing

there is a file called: rendererDX11Monitor.ini

open it with notepad, find the option 'fullscreen' set it to 1. save file, try again.

That file shows I have 1 next to the fullscreen and also a 3 for the AA, but still it launches without both. I even set permissions so that the entire folder is able to be edited and not on "read only" too.

I wonder if this is related to when I first installed the program I couldn't launch it through steam and gave me an unknown error. I followed the iRacing instructions which was to change directories to see what the log is through the CMD window, but it would say "access denied" even after allowing user permissions for the entire folder to be accessible. I do have the game installed in a separate hard-drive than the OS too.

I appreciate you trying to help diagnosis/fix my issue however!

I did a reinstall and it seems to be functioning now... Nope, next session the AA stops working. This bottom AA works intermittently, SMAA. Now I'm trying MSAA, it seems more consistent. I was running a dimmer program in the background. Disabling the W10 evening night light + the dimmer maybe has helped. I will report back if I find a solution.

I bought mine through steam, but just installed the client from their website. That allready solves a lot of the problems.

Dynamic LOD can also cause jagged edges that look like AA is not working, especially in combination with SMAA. MSAA is mostly the best solution.

If you have a powerfull enough computer, you can also disable texture compression to up the quality.

Hm okay I'll consider that. I have tweaked LOD and I don't notice much of a difference in changing the value from 60 to 90. SMAA always produces the jagged edges now for me, so I will stick with MSAA. I'm not seeing the texture compression disable option. I'm running a 2060 9700k so a little dated at this point but running ~90 fps online.

You can only do that in the config. I posted solution here: https://steamcommunity.com/app/266410/discussions/0/4333105050948240511/

Ah very cool I'll have to try that out. Thanks for your help by the way. I made a support ticket about this but I'm happy with the MSAA + nvidia AA enhancements.
