I just got an NVIDIA GTX 650 Ti Boost SC, and it runs everything really well. The benchmarks are great, video editing software works fine, and games run really quickly... except for Minecraft. Minecraft runs more slowly than on my old GPU, an ATI Radeon HD 2600.

Any ideas to fix this? 30-50FPS on max settings is what I normally get, which is OK, but I like to install mods like Optifine to boost the graphics, and the FPS would drop. I should be getting like 120FPS in vanilla, and my goal is to have 60FPS (my monitor's refresh rate) with mods installed.

Things I checked/tried:

- I checked the resource usage. Hardly any of my GPU's processing power or VRAM is going into Minecraft, and the CPU is not overly taxed either.

- I have 64-bit Java. I tried 1.6 and 1.7, both with the same results.

- Minecraft has 1GB of RAM allocated to it, and it's not running out.

- My computer is definitely fast enough. 2x4-core Xeons (2.8GHz), 6GB RAM, 1.6GHz bus speed

- I installed the CUDA drivers from NVIDIA, but they didn't seem to do anything at all.

- There aren't any heat problems that I know of.

- I updated my LWJGL. It didn't help.

- It's slow in all versions of Minecraft.

- I installed Optifine, which didn't help the FPS... and then yesterday, the game started freezing after a few seconds because of Optifine. Not sure what's going on here. I can use any mod but Optifine, and this again goes for any version of Minecraft. Disabling advanced OpenGL fixed this, and it works even if I enable it after. The FPS is still the same or worse.

So the problem is that Minecraft is just not taking the GPU resources it should be taking. Any responses would be greatly appreciated. Thanks for reading.

There is a bug with the new launcher that is causing minecraft to run 1/3 to 1/4 the normal fps on intel processors, until a fix is released its going to be slow no matter what you try.

I'm using MagicLauncher, actually. My cousin's game is running well, and he also has an Intel processor.

His processor may be an exception?

Oh, that's about Intel GPUs, not Intel CPUs. I have an NVIDIA GPU.

I stand corrected, sorry for the mistake since i was trying to recall the description from memory. I have no idea what the problem is then. If you havent already file an issue at the website in the link an hope it gets fixed soon:/

OK, thanks anyway. I've submitted the report.

Someone responded that it's the GPU-maker's job to fix this. Minecraft is the only game having this problem, so I don't think it's NVIDIA's fault.

Closed as a duplicate of the "new launcher makes it slow" bug. No, it has nothing to do with the launcher, and it does it for every version in any launcher I use.
