first of all I want to mention it took me a decade to make a Jira account because making a complex password and unused username still doesn't work I tried 3 emails until I finally made this one, anyways I came from Minecraft support because they tried their best and couldn't fix it so most of what I write is from those emails, my issue is the first time I tried Minecraft java it was all good and fine I was trying Optifine to try Shaders until I installed a Shader and suddenly my fps dropped to 5 fps and since then, I removed Shader, formatted my laptop, literally did everything still Minecraft java gives 0-30fps plus extreme freezing when I move so I wanted to see if anyone could help or its unfixable for no reason if anyone who is answering me could just look at this reddit post where I say everything about it https://www.reddit.com/r/Minecraft/comments/z2kzt5/can_someone_for_the_love_of_god_help_me_with_this/?utm_source=share&utm_medium=android_app&utm_name=androidcss&utm_term=1&utm_content=share_button also sorry for not being very specific my settings are on lowest and CPU usage is very high almost 100% and GPU usage is low also lag happens mostly when the game is rendering  (when I just opened the world)  and after that it gives like 30 fps but freezes a lot when going around also another thing, long ago when tried fixing it on my own when I was switching to shader and back to original fast it got fixed for few seconds and it went bad again after few seconds, First the game is like this on shaders and vanilla (no mods at all) and the game is original  please notice my CPU and GPU usage I think that's the problem because my GPU barely gets used my CPU is always 80%-100% also no I am not on integrated GPU its on my main NVidia 840m(it gave a lot of fps first dont judge by the name) also my control panel settings is perfect I tried adding javaw.exe and turn it into high performance in setting same for control panel so that's all sorry if I duplicated everything because I mostly copied it from the emails, thanks for helping.
