Witcher 3 - Drivers & Tuning

A lot of gamers in our forum and at other places on the interweb are having fun tuning The Witcher 3. I'll post a couple of random infos and links to support you in your quest.

• nVidia released a new optimized driver 
• You own a GTX Titan X? Congratulations, nVidia has a free The Witcher 3 for you!
• An optimized driver by AMD should come out this week
• GameStar's technik check (->traffic light system) gives you a good idea whether your PC can run the game. Just go through (1) graphics card, (2) CPU and (3) RAM. The weakest color counts.
• PC Games Hardware analyzed the performance of 22 graphics cards and the CPU scaling. Surprising result: If you have a decent CPU with at least 4 cores, The Witcher 3 is graphics card limited even on 1280*768 without AA/AF and post-processing!
• nVidia published a very detailed tuning guide
• The first dozen SweetFX profiles for W3 have been created. Here's one random video to get you started.
