Meant to be Seen

I am able to get the Yooka Laylee fix starting through DX9 mode but I see many textures and effects are only appearing on one eye.

Haven't tried DX9 mode yet but it is like this in TAB mode also. I think it may have been this way before geo11 too since they updated the game and broke the fix.

Same problem here in SBS latest drivers. I doubt its the patch, seems to be a few single eye rendering issues with Geo-11. Could be related.

I remember looking at it (in 3D Vision) not too long ago, at least the GOG version, and not being broken. But my memory could be failing me. Anyway, I'll get to refix this for geo-11 at some point. It's my plan for the majority of my fixes, eventually.
I can't do anything about DX9 not working correctly, though. That's on the side of geo-11 development.

I tested it in TAB mode on my laptop - fix still works perfectly for the 15 minutes or so that I played it.

I was having the same problem with Control with DX9 mode, then I moved the convergence all the way to both sides, also I moved the depth till everything showed up on both eyes and started to make adjustments from there. I'm on driver 516.59 and 21h2. using 3d vision 2 hardware.
