So, there are only 2 months i have got a new computer, but my minecraft is having an extreme low perfomance, no matter what i do! not even optifine could fix this!
note: i have 64 mods
Computer stats:
Windows 8.1, 8 GB of RAM, 1TB of HD, intel core i7-4510U 2GHz, my graphic card is an AMD radeon!
So, the problem is that most of times my fps is low (about 5-20) sometimes i have a lot of lg spikes, sometimes, it takes MINUTES for new chunks to load, and when they load, it load only a few more chunks, then, it takes minutes for more chunks to load again...
