What are your specs and Graphic driver?I have laptop with shaders maxed and it runs perfectly.I crashed once and thats because i added 6 other mods that were heavy so i would advise
1.Turn the game graphics down before turning the shade on
2.If 1 fails , Download a " Lower " version of your current shader (Example: I have shaders that come in like 4 different folders. Low , Medium , High , and Ultra high )
3.Make SURE ( This is SUPER important) if you have intel graphics like me , Your Graphics are on the compatible list.
If none of this works , You're computer specs may be too low to run it.
Edit: Oh you're Nvidia ?..... Ok well then 1-3 should help you out Oh and try to turn the fog off. That helped me crap
loads after i crashed with all those mods lol
