No, it didn't help. I created a new Wine prefix and re-installed the game as well. If anything, it's worse. I'm not getting any joy, even if I cycle the Windows versions.
Seems like a pile of garbage :-(
I also tried it in Proton via Steam - no luck there either.
Strange... I have been playing and i beat 3 bosses and it plays well. Also i play with dxvk and fsync and it works well. There are a few problems of frame passing but nothing serious.
For reference i'm on Manjaro using a RX 580.
Yes, it is very bizarre that I seem to be the only one who is having problems running MGS 1. Other Windows games seem to run in Wine just fine for me. For example, KOTOR and Oblivion recently.
I am using a variant of Arch Linux on a very typical Dell desktop PC with an NVidia GTX 1050 GPU.
I tried installing DXVK in my Wine prefix, but if anything it made things worse. In fact, it seems to have screwed up my prefix for the other games I have on there, so I had to make a new one. None of the games I tried seem to run well with DXVK.
I have posted on the WineHQ forum as well, to see if anyone there has any suggestions. I will keep trying different things and I'll post again if I figure anything out.
