An old Direct3D problem with Nocturne (plus Blair Witch Trilogy) #336

Closed Zerodarkage closed 1 month ago

Zerodarkage commented 3 months ago

image Using Direct 3D mode causes this anomaly on some parts of the 4 games. I don't have a clue why... It's like some effect is not working correctly. Some levels the char disappears completely...

Any way to fix that with an option or do you need the debug log?

Do you have a save game or some instructions on how to quickly reproduce the issue?

I found something interesting! The bug does not happen in DDrawCompat-v0.3.0!

P.S. I think DDrawCompat-v0.3.0 doesn't support hardware acceleration (at least in this game. I really don't know xD)

Thanks, I can reproduce the issue with your save game. I was worried it was going to be specific to old Intel GPU drivers, but luckily that doesn't seem to be the case. I'll try to figure it out.

This should fix it: ddraw.zip (diff.txt compared to v0.5.3)

Yes!!! It's fixed!!! Thank You Very Much!!!

P.S. Devil Inside (and others) has problems with textures stretching "to infinity and beyond!" Did a quick test with Devil Inside! It's fixed too! :D (Maybe was already fixed since the original 0.5.3)

Do you think any compatibility mode option is needed for Nocturne and Blair Witch Trilogy??? (I did some tests and seems to run fine without any of them). Thanks in advance!

narzoul commented 2 months ago

If it runs fine, then no.

Fixed in v0.5.4.
