So, I made a "modpack" for me and my friends (just threw a bunch of mods together) for 1.15.2 version to play with my friends. I made a server with the same mods and run it on my pc parallel with my mc but i think it can handle both since my pc is pretty decent. I have only about 30 mods and most of them are just small Qol mods that dont practically add anything new to the game and weigh mere Kb not even 1 mb but i do have mods like botania and etc that are a little bigger but only like 5 of big mods. My pc specas are: i7 7700k, GTX 1080, samsung 1 tb ssd (windows and minecraft are both on it) and 16gb of ram (but its quite slow ram, runs at 2133hz) but that was enough for ftb academy modpack which had a lot more mods and i ran it plus the server both on my pc and was getting great fps (limited it to 144 fps due to my refresh rate on my monitor and it always was 144 only dropped to like 120 fps when there were a lot of particles like rain) but im surprised my pc cant handle only 30 mods on 1.15.2 version. So can someone help me? I dont think there is a virus or anything on my computer because task manager doesnt show any processes that eat ram/cpu/gpu and shows that the only programs that are using them is minecraft and discord others processes use only about 10mb or so and dont affect cpu at all. When playing i also close my Chrome browser because it eats ram like crazy.
