Mouse lag during tactical missions

[Magician]

I must admit that this game has truly developed in the spirit of X-COM, and have been truly enjoying it, especially the wealth of background material which has been prepared in the UFOpedia.

Unfortunately, I have been encountering an issue which remains in spite of all my efforts.

Although the mouse moves at a normal speed at the menu and geosphere, with hardly any differences from its usual operation on the desktop, this changes as soon as I enter a tactical mission. It immediately begins to lag.

It seems to be isolated only to the mouse, as commands from the keyboard are executed immediately. I also noted that going to the options menu (while in tactical combat) removes the lag experienced -- but this returns if I attempt to change the video settings from there.

This has persisted, even though I opened the task manager to ensure that its process was given a High priority, and also brought down the video and music settings to the lowest possible settings.

My question is: can I do anything about this, or should I await a future release?

try to deactivate the threaded optimization in the nvidia control panel - see our faq for more info about it

[Magician]

Thank you, that solved it perfectly

I have the exact same problem..only, i'm an ATI user :/

2.5GHZ Celeron
1.2GB Ram
256MB Ati Radeon x1300
XP

How do I fix it?

On another note...shouldn't i get more than 15 fps in mission mode?

[cronodevir]

No answer?

[BTAxis]

It would seem not.

[cronodevir]

Oh well...

[blondandy]

this is not as helpful as you might like.

it is probably something to do with you graphics card (or maybe vista). fiddle with the settings. if you work it out, be sure to write it up on the wiki FAQ.

I assume you have already switched off the aero theme.

[cronodevir]

Don't have Vista..never heard of aero theme..

Right now, i'm not even trying to fix it. As i have seen no point. Maby later versions will work, i dunno.

[blondandy]

ooops. Magician had vista.

i assume you have got the latest ati drivers.

but really, why not crank open your gfx card options and play?

[cronodevir]

I have the latest ati drivers, its just, there isn't anything really on my card that could effect the game..i think, all hardware options like aa and ansi are all off, and so is the pixel what ever its called. I am not sure there is a vsync option, also, it was most laggy near the transport.

also, 15 fps?? i should be getting a good mean 60 fps...

closer look at my stats:
