1) you need to use the open-source drivers
2) you need to compile wine with the gallium nine patch or install an already patched one

Ps. On Nvidia I've tried with Nouveau with no great success, the best situation is when you have an AMD card!

Ps2. if you're on ubuntu check this external repository

↑ This. Gallium-Nine won't work with NVidia's proprietary drivers and your GTX 960 looks really bad performance-wise on nouveau (open-source drivers):

If you're using the Open Source AMDGPU drivers you enable NINE the same as CSMT with nVidia cards in winecfg. Just make sure you are running a NINE build of wine. Otherwise the option will not be there. I'm running AMDGPU and WINE-NINE on my Radeon RX480 in my little computer (Dell XPS 8700, CPU replaced with a Pentium Dualcore Haswell CPU, I can't remember the model number but it's an unlocked chip). It's actually very impressive in titles like World of Warcraft.

As crt0mega said, NINE is not for nVidia or AMDGPU-Pro driver installations. Use WINE-Staging and CSMT for those.

Yep,as others have said... Better off sticking with pro drivers if you're nvidia user. Csmt+wine is your best bet for performance. Nine is for AMD Radeon open source gamers, you could use nouveau with nine, but its not as well supported and performance probably doesn't match pro drivers on nvidia.

If you're on Arch/Antergos, Wine-Staging-Nine is now an official package:
