Hello guys.

My mouse gets very slow in interface screens of game, but space navigation is all fine. Is it bug? Or is there workaround?

Could you give some specific hardware/software configuration information?

AMD Athlon 1500+, 1Gb, GF5500FX, WinXP SP2, A4 Mouse :)

Which A4 mouse? What version(if any) mouse drivers?

SWOP-35PU (i guess SWOP-35 model). Tried both official and standard windows drivers.

Ah, perhaps it's a sensitivity issue? Is your mouse consistently slow(it takes much scrolling to move your mouse) or is it intermittent and jumpy slow?

The former might be fixed by increasing your "pointer speed" in Control Panel -> Mouse -> Pointer Options. There may also be a way to set that within VO...somewhere. You'd have to check around in the options menu.

Jumpy slow. And sensitivity set to nearly maximum.
Anyway I've bought new computer yesterday and going to try it on new configuration.

I have this problem too.

Logitech mouse. AMd 3200+ MSI RS480M@ mobo ATI onboard.

Edit: Windows XP Pro

Options --> Interface --> Show station in interface (untick)

Makes station menus look a bit dull, but the speed-up is worth it if you are having issues.

What Yoda said. It's the graphics lagging you. You can also turn down detail levels to increase framerate.
