silviuf: Hi, I had the same issue, while trying to play Arcanum on Windows 10 (on a AMD 290x card). Guys, I just want to say this: this game is not worth playing on W10, even though somehow you might succeed in making it run fine (somehow); this game runs flawless (with the same run commands) on Windows XP.
So, what I did:
- I started up a VMware Windows XP instance (easy to find, fast to install).
- Be sure to set the VMware preferences\Display screen option to "Stretch guest"; otherwise, if you leave it on automatic, the OS might run fine, but the game will run centered (actually, that is the 640x480 size, I think). With "Stretch guest" it will run full screen, like on a normal OS installation.
- I installed Arcanum with the same commands I found here: -no3d and -triplebuffer (or double, I am not sure if the latter really helps). Without these commands, even on WinXP, the game exhibits cursor trailling; I think the reason for this is that I am using a modern graphic card, even though I am using now XP; as I read over the internet, this game was meant to be played on a Voodoo card, or equivalent.
- I deleted the ddraw.dll file from Arcanum game folder (mandatory). With this file ON, the image was still corrupted. Still I am not sure how this game works, without that ddraw.dll: does it use the ddraw.dll from the system folder? Does it revert to DX (highly unlikely)? Why doesn't it work with the original ddraw.dll, why must I remove it?
I tried to make this game run on W10, with the above commands, and even after I deleted the ddraw.dll. Eventually I could play it on W10, but the cursor was laggy in the conversation text lines, the screen scrolling (both mouse and keys) was awkward and, worst of all, I experienced low fps in certain areas (to a downright bloody slideshow). Example: I started the game, I played like 5-10 minutes, and when I entered in the first cave from the first map (that one with the cursed spirit), my screen was turning into a slideshow, literally. It would come back to normal whenever I would Alt+Tab to desktop and back into the game (although this usually crashed my game). This issue appeared every time on W10.
Now this game runs flawless on WinXP: no low fps, no scrolling issue, normal cursor behavior, it's perfect. If I am to blame someone, I blame GOG, for they were not able to modify the installation files so that this game works proper out of the box. This game needs fixes also on WinXP, which is not normal. As a comparison: I installed yesterday Fallout 1 (GOG) on Win 10, it works absolutely flawless, it even has a 1024x768 resolution. How can Fallout 1 work better than Arcanum, which was released 4 years later?
Sadly, running on a Windows XP VM still creates the same problems for me. The game is very laggy in battles and sound echoes incessantly. Not sure what else to try.
EDIT: Strangely, the game seems to work way better in Windows 10 than in the XP VM. I used all of the regular modifiers like -no3d and -triplebuffer, in addition to running the game in Compatibility Mode (WinXP SP3). The game is a little bit laggy with a few artifacts here and there, but it's not unbearable and the music doesn't echo anymore. Dialogue text is fine too.
