Hello, problem see topic.

Win 8, Quad Core, 8 GB RAM, put Arcanum to run with nVidia card and running as admin, tried -no3d and -doublebuffer and xp mode, but still scroll with mouse too slow and fights with more then 3 enemies too slow, but what is funny, that if you switch to desktop and back it will run nice, but then you have pink tiles and mountains and earth floor for example gets blurry or something.

Hires-mods, unoffical patch are installed.

Does it have to do something with ddraw.dll file? maybe too old or something?
Run only with intel card?

Ok, i think i found already my own solution, but first:

1. tried newer version of ddraw.dll and it was even more slow, forget it, btw i think GOG fixed already ddraw.dll cause in details of ddraw.dll you see already Arcanum fix written.

2. switched off nVidia card and started only with intel card and it worked, scroll with mouse is faster and loading between areas is also fast, but also deleted before -no3d and -doublebuffer and also started in win 8 mode.

So, for me intel card was the solution, maybe somebody will find it helpfull.
