I've just started playing Minecraft again after taking a break for like 3 years. But now when I try to play with shaders, it's not working.
I have downloaded the latest optifine version, I have shaderpacks that's support 1.19 (the latest version of optifine). I can see the shaderpacks in the meny in-game. But when I press them (I have tried with 3 different shaderpacks) the game loads for a quick second and its still looks like vanilla. I don't see any messages in the chat. I can see when I press "f3" the game runs on my qpu (gtx 960). My first thought was that my gpu was maybe too old? But I know I have played with shaders before and I don't know what the problem can be.
(I'm playing on java edition)
