The game wouldn't work properly for me at first, The Konami logo wouldn't come up there would be sound on launching for the startup videos, but they seemed to be compressed into one line at the top of the screen, on skipping them the menu also didn't work correctly, black screen when bringing up the main menu, no appeared, in game was a black screen apart from the HUD overlay(radar etc) and the nothing but background in the Codec sequences.

Got around this by deleting the dx8.dll from the bin folder in the game directory(where the game exe is) as changing the settings didn't help any.

This may help others so posting here.

Maybe I could try some other Directx wrappers.

System:
Threadripper 1950x, AMD Radeon Vega64, 32GB ram, plenty of drive space, Windows 10, all drivers etc updated.

IIRC, GOG has a partnership with Dégé's excellent dgVoodoo2, so it is likely what's installed with MGS2. dgVoodoo2 has a configuration program, I don't know if it's available with MGS2 (I didn't buy it... yet ?), but you can get it by downloading dgVoodoo2 here.

Not using the wrapper (as you do since you deleted the DLL) often means the game will use the iGPU, unless you don't have a dual graphics system. Most laptops have two GPUs, nowadays I'm not quite sure how it goes with desktop computers, but I think desktop CPUs are graphics capable too, so it depends whether it has been wired in or not.

I've since tried it with the standard release of dgvoodoo2 and it works, the build supplied with the gog release has a configuration program but it's a lot more limited than dege's config utility.

Running on a desktop with no integrated graphics so that's not a thing for me. either way it's working now after V's patch and some tweaking, so all good. just thought I'd post in case anyone else was having trouble with it.
