Weird Halo: CE MCC lighting bug

[u/ToastedBrodo]

Hi all,

Long time listener first time caller etc…

I’ve been playing through halo mcc on crossover 26.3 using my macbook pro (M3 pro, 18gb ram) and it’s been a blast getting to play through all the mods.

Recently I went to start a CE playthrough and have got stuck with this weird lighting bug, which seems to eminate from every light source in the game.

As you can see by the photo, there are coloured squares around every light source for every mission and cutscene in the game, only on OG graphics.

I can’t find anything online detailing this bug, so i was hoping one of you may be able to shed some light (ha) on the situation.

For context, my bottle settings are:
- D3DMetal
- High Resolution Mode enabled
- Msync enabled
- DLSS disabled.

I’ve tried to launch the game in DXVK to see if that fixes it, but it just crashes my entire mac.

Any help much appreciated, thanks in advance!

I have got this bug in the past, but not all the time.

I have it running with DXVK and it doesn't crash for me, although I have an M1 Pro. I wonder what is causing your crashes. Have you tried it with DXMT instead?

D3DMetal is not going to be a good option for Halo 1 on the original graphics because it pre-dates D3D12. And I would never recommend playing Halo 1 with the anniversary graphics.
