Crash shader

Bonjour à tous, je vous remercie d'avance pour la lecture.
Eh bien voilà, je rencontre un problème lorsque j'essaye de jouer avec un shader...

Je m'explique : Je lance minecraft avec forge, je me connecte à un serveur, et déjà là, énorme chute de fps (20/25) ... Quelques instants plus tard, le jeu crash, et me renvoie ceci :

---- Minecraft Crash Report ----
// Don't be sad. I'll do better next time, I promise!

Je précise donc que je joue avec un PC Portable, avec la configuration suivante :
-Intel core i5-4200h, 2,8 GHZ
-Gtx 850m Nvidia GeForce
-8GB de ram
-Et Windows 10

Je précise que j'ai regardé un peu les posts à ce sujet sur le forum, et bien entendu, j'ai déjà lancé le launcher avec "carte graphique hautes performances"...

Merci d'avance pour votre aide !

 

Après vérification, j'ai éfféctué les mise à jour de mes pilotes, mon jeu ne crash plus !
Par contre, mes fps sont toujours bas (25), malgré que ma CG est bel et bien utilisée pour faire tourner le jeu...

(Pardon pour le double post...)

 

J'ai testé plusieurs shaders, notamment SEUS (standard), chocapic (Lite) et Sildurs Vibrant Shaders (Lite).
Quelque soit le shader, mes fps restent malheureusement extrêmement bas pour ce que j'ai...

 

D'accord, merci beaucoup pour vos réponses !

 

Oui ! :)
