Terrible mouse lag

[andciocca]

I like very much the new version of the game and I think it's the best Ufo game ever realized, but I'm having a terrible problem. In certain situations, I'm experimenting  a serious mouse lag. The fps are always 50-60 but the mouse is really slow. I tried to disable sound, to deactivate all the background programs, but the problem is still there. Does anyone know what can I do?
P.S. Sorry for my English

I have never experienced a lag myself. Maybe you can give more information about your hardware, operating system and mouse settings as well as an explanation what in detail you mean by "mouse lag" (jumping pointer, frozen pointer...)?

Maybe you can avoid this by setting the process priority to normal as mentioned in another subtopic of bugs & features. But If you say the rest of the game is not affected I do not think this has too much of a chance to work. It will not hurt though.

You are right. I missed some informations on my hardware. My system is:
AMD athlon 64 3500+
2 GB Ram
Video Card Geforce 7800 GT
It's strange because with the previous version I didn't experience this bug.

What OS? (I will move this thread to the relevant forum depending.)

[andciocca]

The OS is Windows XP SP2. Finally I've solved the problem simply changing the priority in the task manager from high to normal (as someone suggested me . But anytime I run the game I have to change the priority. Now I can enjoy the game that is really fantastic

you can also use the cvar sys_priority to set it (use the game console and tab completion to get more infos)

Ok thanks all!

If you want it to start at normal priority (on Windows) automatically, make a .bat file somewhere on your disk and place a shortcut on your desktop.

*.bat:

start /NORMAL drive\path\ufoExecutive

That is, if you still need to fix this problem.
