I have been playing Minecraft for some time and earlier on the 1.8 I had about 60 to 100 FPS with shader. Now I'm currently playing on the new 1.14 and have the same Shader effect only 20 to 30 fps why can that be? Do you have any tips?
With the 1.14 you have more stuff inside than in the 1.18, which just consume your power more.
In other words, your PC is now too weak in the state. That means you need to upgrade your PC's performance.
Ok, but only because of a few new items and I already have a 1070 ti in it!
It's not just "few" new items. There are tons of new items as well as animals, and especially the graphics are getting a lot weird from version to version. Since it may be that your 1070 Ti already with a shader, which massively takes away the power, not enough. Incidentally, the processor also plays a role in FPS number. What kind of processor do you have - out of interest?
