ok so basically I bought an acer nitro 5 laptop which had a graphics card of gtx 1650, the fps for Minecraft java with sildurs shaders was only running at 12 fps, I assumed it was an issue with the specs not being good enough so I returned that laptop and bought a new msi one with a graphics card of rtx 2060. I know its not an issue with the specs now since I am having the exact same problem on the better pc as well
