For some reason, I can only get up to 30 fps on Tekkit & Minecraft. In Tekkit, I let it use 12 GB of ram. I have tried letting java use 12 GB, but to no avail. I have tried tinkering with the settings, nothing. Still slow.
My Specs:
(Lenovo Y70)
Intel i7 Quad core
16GB RAM
Nvidia Geforce GTX 860M
Message me if you need anymore info.
Thanks in advance!
