In the title. I just bought the game on GoG assuming they had ironed out the problem Steam has, as they usually have, but as I should have been aware there is a connection between making assumptions and becoming an ass.

I only have the option of Software mode or Direct 3D and I'm not using software because it's lighting effects are crap, there has to be a way to use DirectX in 2015 with acceptable fps. I've tried two other configtool.exe (one from the Demo and one from the 1.34 patch) and neither work, they just show an unspecified error (yellow triangle) and my current/default Configtool.exe shows neither DirectDraw or Glide3 (I've got nGlide librarys in the game directory.)

How on Loki's sack do you get this game to work as intended, but on Windows 8.1? (software mode is not as intended!)

I'm building quite an unhealthy rage after 3 hours and if it wasn't for fond memories of this game a decade ago I would just uninstall it and give Inquisitor a try.

The NlsEng.dll file also needs to be changed in order to use the disk version configuration program with the latest download version of DD, included in this download (rename, or otherwise back up the original files, then extract the zip file into the main DD install folder).

For the performance problem, check out:

Windows 8 slow graphics problem fixed using WineD3D

Windows 8 Performance "Patch"

By George, Raze..! The above-mentioned patch (Win 8 Performance patch) completely fixed the D3d problems I'd had with the game...! No more stutter and freeze..! All gone, & now plays as fast as the software game.

Oh, yeah...forgot to mention that the 8.1 Windows problem still exists in Win10x64...so this patch works just as well in Win10. It's kind of funny, but I bought the game when it was new years back and this is the first time I've gotten it to run properly in D3d mode...;)

Thanks for the link!

EDIT: Moderators, please sticky this thread!

The performance fix works like a charm (Win10 x64). The loading screens are garbled, but the game itself runs perfectly fine.
