I had the fog and sky rendering issue after a Windows 10 migration on a W7 laptop running an Intel HD Graphics 3000 and a Nvidia GT555m (Dx10).
I tried to fix it with DgVoodoo 2 (2.54 to be precise) which was great for à Dx11 card on an other W10 PC (GTX 765m). But it was a failure because DgVoodoo2 wrapps games on Dx11 cards, not on Dx10 and olders ! So I tried DgVoodoo 1.50beta2 with a great success.
So remember that you can solve the Fog & Sky rendering issues with :
DgVoodoo2 for Dx11 cards DgVoodoo1.5beta2 for Dx10 and probabely older cards.
For Dx11 cards : 1. Download the latest DgVoodoo 2 zip on Dege' site 2. Copy/past the content of the MS folder + dgVoodooCpl in the Hardwar folder 3. Launch dgVoodooCpl and chose an adapter with 128Mo in the DirectX tab 4. In Hardman (the Hardwar launcher) Display tab, uncheck 32 bit textures Enjoy This can help too hardwar.proboards.com/thread/679/rendering-issue-1920x1080-scaling-solved
For Dx10 and older cards : 1. Download the dgVoodoo1.5beta2 zip on Dege's site 2. Copy/past GLIDE2X.DLL, GLIDE.DLL and DGVOODOOSETUP.EXE in the Hardwar folder 3. set dgVoodoosetup.exe to Windows XP compatibility mode. No need to run it and tweek options if it works like it is... 4. In Hardman (the Hardwar launcher) Display tab, uncheck 32 bit textures Enjoy
