I reported this bug to nvidia: https://devtalk.nvidia.com/default/topic/773623/linux/character-models-are- sometimes-invisible-in-the-witcher-game/
Hey,
nvidia guys are requesting more details. I have provided a post, but for some reason I've fallen victim to the auto banner of the nvidia forums. Please repost this:
As mentioned in the wine bug, it happens all the time to people using primus/optirun. The bug does occur when running an application directly on the nvidia card (via directly attached to the device display port) but much more rarely. It also occurs with nvidia prime setup but much more rarely.
Tl;Dr;
You need a dual video card machine where the nvidia card renders through bumblebee in order to get the bug every time. Otherwise it is a hit or a miss.
