I installed IWD2 (old CD version) on my windows 10 computer. It can run perfectly well in windowed mode, but when it's in full screen, it gets lag all the time. Does anyone know how to fix this?

i've tried run in xp service pack3, disable full screen optimization, turn off vsync, but none of them worked.
Please help me. Thank you ><


my computer info:

windows 10 home edition

intel i5-6400 2.70Ghz

8192MB ram

Directx 12

Nvidia GT 720

Try this DirectDraw wrapper: https://github.com/narzoul/DDrawCompat/releases

Use v0.21, not the experimental one (though I haven't tried that one). Simply extract the ddraw.dll into the Icewind Dale II directory.

Edit: Better first try the IE DDrawFix: http://www.bitpatch.com/ie_ddrawfix.html

Sorry to hijack your thread a little but did you have any trouble launching it inthe first place? I lose mouse functionality and the game never starts on my end. If you have do you recall how you got it working on Windows 10? If not sorry again feel free to hit me with a negative rating!

I am having same issues, lag and flickering and just issues period in Win 10.

You do have to change your Win DPI setting for the exe to be app controlled if you have your DPI higher due to higher resolutions.

Can't figure out the rest of the issues though.

If someone still have this problem, first try to deactivate G-Sync, Free Sync and V-Sync. This was the only thing helped me. Looks like the game can't work with the sync. Game is running fine now without doing anything else.

Don't forget to delete the ddraw.dll

If anyone else is still having an issue, try using cnc-ddraw from Github

v0.21 download worked perfectly for me. Replaced the old DLL in my game folder and now 0 performance issues
