So im lookig to stream this game using obs, and i cant get the capture working.

Any advice on how to get it to capture on using OBS?

Попробовать запустить в окне через DxWnd если речь о классической версии

I just tested the game (higher-resolution version) with OBS game capture and it worked 100% fine.

I created a new scene with a new source (game capture, capture specific window), started the game and minimized it, clicked on the new game capture soure and added the [Diablo.exe] DIABLO to it. Then I went back into the game and in the OBS preview screen the game was showing up.

I found I needed to use Window capture.
