Not necessarily, but if you need to use double buffering, I'd try with the HiRes installation instead of the switch. Just in case :P

By the way, it is enabled by the HiRes patch by default, so unless you changed it in config.ini, it should already be using them.

I see. Thanks for the help and the info, working perfect.

No problem. Enjoy!

I'm sure with some troubleshooting we could get things working, but I recommend you start over from scratch with a new installation and use the new 1.5.1 UAP only:

thank you very much

Worked perfectly. Arcanum is running as smooth as butter.

This finally did the trick for me. Thanks!

With all the fixes and wrappers I've stacked on top of one another by now, I was starting to find new and exciting problems (like rectangular fragments of the loading screen showing in place of character shadows) on top of the base ones

I have tried everything and when I did all of the things mentioned above I get that buggy screen when it starts with green and when I get to the menu splits the screen to blue and black. Can somebody help please?

Tried everything hoping it would fix my problem but I seem to have a problem that no one else has since I looked everywhere and no hint of this issue has appeared anywhere for some reason after watching the intro I seem to be stuck in an empty part of the map with a naked shopkeeper and a chest

Sorry I know that I'm a couple of years late with this but I just wanted to let you know that there is a solution for this. You can run the game at a lower resolution and use DxWnd to turn the game into a borderless window upscaled to your monitors native resolution.

Same question. Does someone know how to make the movies scale to fullscreen? (keeping aspect ratio, as set in my GPU settings)

The 0.31 version of ddraw compat did wonders for me.

Can't post links, google this : github narzoul ddrawcompat releases

The game now runs as smooth as butter.

I also installer drogs unofficial patch 2.02

Oh My GOD. Thank you. the ddrawcompat worked like fuckin magic. Not sure if anything bad will happen, but right away, all good.

This seems slightly out of date compared to the current DX installation instructions
From their site: https://github.com/elishacloud/dxwrapper/releases

Instructions:

1. Download the dxwrapper.zip and unzip it to a folder.

2. Determine which .dll file is needed for the game. This depends on many factors which will be explained on page created later. Most commonly it is ddraw.dll, dsound.dll or winmm.dll.

3. Copy this .dll file from the 'Stub' folder plus the dxwrapper.dll and dxwrapper.ini files into the game's installation directory, next to the main executable file. For some games the main executable is in a subdirectory (like 'Bin', 'Exe' or 'App') so the files will need to be copied it into that directory. Overwriting existing game files is not usually recommended.

4. Open up the dxwrapper.ini file in a text editor and enable the settings needed for the game.

Note: Try the options under the [Compatibility] section first. For many games these are all that are needed. See the Configuration for details on the options.
