This hotfix is from the R418 branch. WDDM 2.6 is not yet available.
nVidia simply ran out of numbers in their current branch so you’ll see a big jump in number for future drivers. As for drivers for Windows 10 19H1, nVidia says stay tuned.
- Tom Clancy’s Ghost Recon Wildlands: Game crashes when accessing the inventory menu
- Ark Survival Evolved: Fixes random crashes on GeForce RTX 20 series GPUs
- Fixes corrupted graphics in games on ASUS ROG Strix GL702VS notebooks introduced in driver 419.35
nVidia is still not having any luck reproducing The Witcher 3 crashes. They made a new sticky thread to try and capture more information to help. Most likely it’s some corruption in Windows. Games are usually tested with fresh installs of Windows.
