I am playing the Witcher right now, and it's a pretty good game. Unfortunately it does not utilize dual core CPU's so it maxes out one core. This is fine in every way except it often causes mouse lag. I think this is because I am using a USB mouse and it requires processing power to run (and it probably doesn't support multi-cores either).

Is there any way to assign my mouse to run off of the second core? Or would a USB/PS2 adapter get rid of the lag?

I have tried fiddling and turning off logitech desktop manager but this doesn't seem to work.

Is this a wireless mouse?

I’m not a gamer but try going into task manager; you can set the processor affinity and the priority. I’m thinking that if you are able to move Witcher to the second core and move to high or real time it might help you out a bit.

I didn’t read the end of your question. I don’t think you can move the mouse to the second core but it would be a good place for your game.

yeah it is wireless. normally it is not laggy at all, just when the cpu is under full load.

thanks, i will try changing priorities.

See if you have a wired mouse. Although it might not be the main problem, it could be a factor.

If changing the priorities dose not help, try changing it over to the other core. Most stuff runs on the first core by default so most of the time the second core will not be used much (processor affinity).



Just remember that you will have to reset the processor affinity and the priority every time you start that program or restart your computer.

already suggested. plus, the task manager automatically delegates new tasks to a core that's doing the least work atm (well it should, anyways).

how do you do this?

also, would a ps/2 adapter use different drivers and get rid of slowdown?

Open up task manager.
Go to the processes tab.
Right click on the process you want.
On the bottom of the menu are processor affinity and the priority.

I would try the PS/2 adapter. It should help some but I don’t know how much.

I disagree with that comment with XP but it did get some what better with Vista.

I’m not a gamer…

At least Vista does the job pretty good. I wouldn't know about XP coz I've never run XP on a multicore system... but I though it had a good multitasking support or whatever it's called... oh, well.

@oregon - if it's a gaming mouse and it's got extra buttons, they *might* not work when the thing is being used with a PS/2 adapter... what type of mouse is it anyway?
