PhasmaNL: Besides this issue, the mouse also moves very awkward. I think there's some major mouse acceleration going on. Really feels terrible. Anyone else seeing this problem?
This is only happening in the enhanced GOG version.
Lebesgue: Yeah, I have the same issue. Mouse feels really hard to use. As you wrote, there is some acceleration going on so that small moves are OK, but large mouse moves make the cursor go crazy... And this happens only in the enhanced version.
Try set the mouse to 125hz 400 or 800dpi when playing the game. it did solve the huge mouse isue on speed in Diablo and in this game for me. I have MarkC_Windows_10+8.x+7_MouseFix installed dont rly know if it do effekt it. Did install it for Dablo when trying to fix the problem and dosbox. Changing the report rate, can be a solution.
The mouse running out of screen is not related from what i can se on my few tests.
