FPS issues?

[Jojash]

So, recently, I've been playing Tekkit and I seem to be experiencing some serious FPS issues, sometimes to the point where the game is unplayable. It seems to be worse if I'm idle for a while and I come back or if I look at a jungle. I don't believe it's to do with my computer as it can run other games, such as Fallout 3 or Borderlands 2, on the highest settings with no lag whatsoever, I've tried playing around with the video settings on Tekkit but they seem to make no difference whatsoever. If anyone can help I'd be very grateful!

Try turning off IC2 sounds in the IC2 config file.

That has helped somewhat, it doesn't seem to lag after idling as much, but it does still have quite bad lag when I'm looking at jungles.

Tweaking the settings in Optifine should help. Are you using a hi res texture pack?

also make doubly sure that you are using 64-bit java if you're on a 64-bit machine. the launcher has a habit of using 32-bit even when you try to tell it not to.

Not wanting to thread-jack but how do you do that?

You uninstall any other Java's you have and then download the correct one.

I am using 64-bit java, it's the only one I have installed.

I've tried switching to the default Minecraft texture pack and that's made no difference. I'm not sure what you mean by Optifine, but if you can point me in the right direction, I'll certainly give that a go, do you have any suggestions as to what I should be tweaking?

[Jorcer]

Optifine is a mod included in the pack that alows for way more graphics options. I am on my phone atm but when I get on my computer I will edit with some sugestions.

Thank you very much, I eagerly await your suggestions. :)

Your graphics device isn't being used by tekkit.

This is very possibly your issue. Do you have an NVidia card?

I do...

[Jorcer]

There is an issue with NVidia cards IIRC, there is also a way to fix it, but I can't remember how atm. I will look and see if I can find what it was.

I may have found it myself, actually, http://forums.technicpack.net/threads/low-fps-in-tekkit.12688/
