[Bug] Performance drop when wearing a Jetpack

[cubicbyte]

When putting on the Jetpack, the performance (FPS) of the client drops a lot. According to my friend, FPS can drop below 10

This applies to almost all jetpacks from yours and the original mod. Moreover, the impact on FPS varies for some.

After looking in the built-in profiler, I found that the cause is in the Jetpack GUI (the one on the top left corner)

@CrossVas seems the code you wrote is laggy

@cubicbyte could you try this one here (unzip it) gravisuit-2.0.3.zip

@CrossVas In general, everything is fine, but there are still minor decrease from 233 to 210 FPS.

@cubicbyte what was the FPS value on previous build? I mean the difference.

@CrossVas You can see on the second screenshot, 126 fps with Jetpack

@Trinsdar @cubicbyte the problem was that I've used vanilla MC's gui class for rendering, while the new overlay uses forge's system, which seems to have less impact on overall performance.

So vanilla has a shitty system, why is that not surprising
