Hi there. First time poster.
I’ve used Lutris on my steam deck for a while now. Most games tend to work with a little tweaking.
Icewind dale 2 is not the case. I’m not exactly tech savvy but have installed it via gog. It loads up and starts. Plays the cinematic. Then lags like nobody’s business. Takes a good 10 seconds to click something. Unplayable like this.
Was hoping somebody had worked out how to plays this
I still have to test this one. I do see an installer which installs a version which runs the GemRB engine. You get a native version and a modern engine.
Thank you for the reply. Yes I tried that and the gog version. The gog version is the only one that opens at all. The Gemrb blurred version doesn’t even open just says playing then stops straight away. Pulling my hair out 
I just want to play it 
Interesting. For the gemrb Linux version I did a ldd on the executable and found some missing dependencies on my Steam Deck.

So for my situation, I need to install these libraries.
If you want to play this game with WINE, you need to disable the multi-threaded command stream feature, as it has a very severe impact on performances.
winetricks csmt=off
The above winetricks fix is for the windows version. Just to make things clear. So there are two options, run a native engine gemrb (and install all required libraries), or run the windows game through wine (and set the winetricks switch).
Right, I updated my message to clear up the confusion.
Thanks for the replies guys. I’m not really tech savvy. Where would I install the extra content for the gemrb version? And to where ?
You mean mods? The game is in the app folder. So I guess it should go there.
Ok. Got the gemrb version to run. Didn’t go past the main menu and the settings screen. Did test the first video from there.
1. Check libraries
As mentioned earlier, all libraries need to be installed. If a not found error is returned, install the library which provides the .so file.
ldd ./gemrb
2. The config script
The config script is taken directly from a baldurs gate game. This is icewind dale 2. And the Lutris installer expects this too. So I renamed the baldurs-gate.cfg to icewind-dale-ii.cfg and put the following contents in it.

The paths are important! I only got it working by using absolute paths. So no ./folder/ but /home/username/games/rest-of-path/ should work.
That’s all what should be necessary.
