The NVIDIA drivers released on January 24,2017 currently cause modified minecraft to crash during startup. If you find your modpacks suddenly crashing on startup, and you recently updated your video card drivers you can safely roll them back to the December 14,2016 version or install the hotfix. Driver downgrade: NVIDIA Driver Downloads - Advanced Search Hotfix: GeForce Hot Fix driver version 378.57 | NVIDIA Update: Latest update (378.66) Fixes the bug.
how do you roll it back exactly? i installed these drivers and am installing the fixed version from december. anything else i have to do/delete the other drivers? if so, how
Go to this link NVIDIA Driver Downloads - Advanced Search and download the version from December 14th or around there. That's what worked for me!
Thanks. I'm so glad when some game seemingly unplayable becomes playable using a relatively simple fix like a driver rollback.
If you require the latest driver for another game, there is also a hotfix available: GeForce Hot Fix driver version 378.57 | NVIDIA
