MSAA Anti-Aliasing Quality in Oculus Quest with Unreal Engine
I'm developing an application for Oculus Quest using Unreal Engine 4.22, everything is fine except the Anti-Aliasing which looks bad. Edges in high contrast keeps flickering and it's very distracting to the eyes.
Using the default VR template for testing, I tried turning MSAA ON (2x, 4x, and 8x) and OFF, and there's never any differences. I also tried a few console commands (in config files and device profil) like r.MobileContentScaleFactor, vr.PixelDensity, r.MobileMSAA, r.MobileOnChipMSAA, r.PostProcessAAQuality, and still nothing... Also, when I turn Mobile HDR on, the app just don't open inside Oculus Quest. I know there's a few posts on this online already, but I could not find any solution, except using Unity instead.
This documentation seem to imply that MSAA is configurable:

The guy here also says that it's possible:

Is there anyone who succeeded to change the Anti-Aliasing quality with Oculus Quest or Go in Unreal Engine 4.22? If yes, how exactly?
Is Mobile HDR supposed to work with Oculus Quest? If so, I would be interested in knowing how to make it work as well.
Is it possible to render at a higher resolution?
Thank you!

he is referring to FFR which stands for Fixed Foveated Rendering and basically improves performance by only rendering pixels towards the center of your view.

I also have the same issue with Aliasing in my build from Unreal Engine when running on the Quest. Like you said turning on 4x MSAA for example makes 0 difference to my visuals. - Most likely need to switch to forward rendering if you want MSAA.

I turned ON Forward rendering and MSAA in my projet settings and it did not do any difference. In fact, I think Forward is always active on Quest/Go even if unchecked. The forward option seems to only makes a difference on Rift.

You're right! Sorry my mistake.- Hello,
Same problem here, no MSAA with UE4.22 and no mobile HDR. I'm reporting the issue. - @demonixis awesome. do you have a link to your bug report. did you file it here: https://developer.oculus.com/bugs/ ?
- Its not a bug, its hardcoded to 4x MSAA
- @demonixis For mobile devices, Oculus hard coded the MSAA value to 4x. Seems like this has been done purposefully to address the performance issues related to it.
- Your project runs with mobile hdr on in quest? Please tell me your secrets!!!!
- How is the problem solved?
- The same i got that polygon spikes and i don't know how to fix thats..
