I know it's super old game to patch but with AMD's rise to being top buy this gen for the first time in forever could we possibly get a patch that remove's Peak 15's reliance on AMD 3DNow which was made defunct back in 2010? Modern AMD CPUs don't have the tools the game is looking for on that level anymore. The console command "viewmode unlit" works to fix the problem but does so by removing all dynamic lighting from the game.
I have lost hope that they will fix this issue by now. Maybe if they ever decide to make a remaster, but BioWare hasn't made remasters yet and EA has only done so very rarely (Burnout Paradise).
There's a mod that fixes the issue: https://www.nexusmods.com/masseffect/mods/71/?tab=files
I don't work for EA.
While I see how that is annoying, you're right, the culprit is that AMD decided to discontinue its own Instruction set AMD 3DNow after 2010.
It would be easy for them to keep it for backwards compatibility, but they decided to put it on the software developers that used a AMD technology...
For the rest, I agree with Fred. The only way that this get fixed is if they decide to remaster Mass Effect.
