Very pixelated mirrors

[Sylosis]

I'm back on DCS after some time off and I had to reinstall the game entirely (the patch was as big as the game, so my drive couldn't take the download on top of the already installed game).

I'm not sure what setting I need to fix to have the mirrors stop looking horrible like that. I recall them being quite decent, but now it's ultra pixelated. I wasn't able to make Print Screen work or to take any screenshot, but trust me, it's really horrible.

I increased almost every setting and it fixed it. I do not know which one did the trick
