Hi, I recently got a new graphics card: Sapphire 7870 1GHz 2GB Dual-X.
Its a pretty damn good performance boost in most of my games compared to my old GTX 560 ti but in Minecraft I have a problem with my GPU usage (only around 30-40%) which results in low frames.
My old card reached well over 100 - 200FPS easily but this new card for some reason doesn't, it only gets around 60-100 Vanilla and 30-60 Modded. I've tried using Optifine but to no success.
I need some help in getting my card to actually do something when running Minecraft, any help appreciated.
Minecraft doesn't like nvidia cards that much, I remember I read somewhere that java always uses intergrated graphics in some cases and you can force it to run on the graphics card, im not sure though.
Possibly but I'm using the exact same setup as when I had my 560 ti in which maintained FPS of over 150. The problem is that my 7870 only reaches around 30% GPU usage in the game. By the way my CPU usage hovers around the 40-50% mark so it can't be a bottleneck.
My PC specs are almost identical to yours but I'm not having any issues. When you play are you rendering any videos or running and benchmarking programs and do you have a lot of junk and viruses on your computer. These are all things that can make your computer slow even if you have the "best computer" in the world. Also check if you have vsync on in the options if you do, turn it off but since you have such a good videocard the game might start to tear.
