Hey there - very excited to have this on GOG, but sadly I've encountered a bizarre issue that I haven't found any information about elsewhere.
On a first launch after installation, the screen goes white and the program seems to hang here indefinitely; the longest I allowed it to sit at this screen was about half an hour. From here, I'm forced to kill the program through Task Manager.
On subsequent launches, no introduction videos play, and if I click to try and skip said nonexistent introduction, I arrive at what I can only assume is the main menu, but missing 99% of its UI. All that's visible are the two flags and Blazkowicz's 3D model. Sounds play if I try to scroll through the invisible menu options, but clicking on any of them causes the program to hang.
This issue happens both with and without the unofficial patch. Any help would be greatly appreciated!

What kind of video card are you using? Are you forcing on advanced graphics settings on your graphics card or anything?

Sorry for the long delay in replying. I'm using an Nvidia GTX 960, and I've left all settings in my Nvidia control panel on their defaults. I should mention as well that the problem persists between reinstalls.
Again, apologies for the delay!

I think I had this problem as well. I had it on cd then got it from GOG but forgot to check where it was installing to.
First it would just crash at start because of nglide. fixed this by setting seta r_glIgnoreWicked3D "1" in wolfconfig.cfg.
Then it ran but was all messed up in menu. so I uninstalled and installed it under Program Files (x86) then had change the seta r_glIgnoreWicked3D "1" setting to 1 again and it ran fine after that. It runs great with iortcw witch you can get from here:

Just need to get the .pk3 files from the GOG installation and paste in the iortcw\main folder
