Serious Performance Problem

[PashPliskin]

This is why I set the client FPS limiter to 120fps with vsync off - it gives a much smoother experience (for me at least,) even though I only have a 60Hz display.

You can dial back the GPU work and change settings to low for planetary rendering. I find that the FPS on planets is at least consistent, which makes a huge difference - 60fps that drops to 20fps often is a worse experience than a constant 45.

Wait...your monitor has a 60Hz refresh rate and you don't get screen tearing with V-sync off? How's that possible?
