My mouse.....

Alright, im using a logitech mx518 mouse through usb, it works perfect when outside of a game, but as soon as I get in a game the response time is delayed and I cant seem to figure out why. Please help!

A few questions first, how many usb ports do you have? - On your pc / laptop - what is it running on?

If the device is linked is it crossing or tangled with any major wires, also do you have any other usb cordless technology linked to your computer, a - keyboard, headphones etc

If you have a usb port on the front of your computer and your using it for the mouse, try the one on the back instead, I had issues with the front usb on my computer for some reason, it may be a unique thing but still, give it a try.

Is the mouse new, second hand?

Have you dropped it?

Have you got any liquids on it or its terminal, very delicate stuff bullet stopper take care of it.

Apart from that at 5:18 in the morning I don’t know what else to say.

Apart from reload the software & try again, and leave you computer spec details so maybe if there is anyone else who had the same problem due to a confliction and can help.

I think about 8 usb ports, it isnt crossing major wires, just other usb wires, we have a keyboard a scanner and a printer in the usb ports.

The problem lies between your chair and the keyboard.

For the record, I have that mouse too - so rep++

Some ideas...

+ What game(s) is the choppyness in? All or some? Direct X or OpenGL?

+ Update your MoBo's USB Drivers if it is plugged into a hub or an extension USB (like the front) then switch it so it's directly into the ports your motherboard provides. (EDIT : Indus suggested this, the reason is because the ports on the front may be USB 1.0 and the ones on the back may be USB 2)

+ Do you have USB 2.0?

+ Has this EVER worked? If YES then delete the mouse drivers and software and reinstall them.

+ Check Direct X Drivers up to date.

MX518... good choice; s'what i have

still, there is no advantage to having a USB mouse...

just use the USB>PS/2 connector you got with the mouse and plug it into PS/2 port...

There are some key differences between usb and ps2, the most drastic being polling speeds but unless you're a hardcore competitive player, you won't notice the difference.

USB has much higher data rates, is hooked up directly to the system's southbridge, so no slow ISA/LPC bus or ancient Super I/O controllers, it uses DMA transfers and relatively few interrupts. It's the future and i'd rather see ps/2 (and com and lpt) disappear today than tomorrow, i like all my ports unified.

The latency difference between USB and PS/2 is in the order of microseconds, anyway.

The only USB problems i've ever had were with older VIA chipsets, and it only affected my mouse, not with lag, but with freezes.

Mach: USB 2.0 won't make a difference, mice, keyboards and other HID USB devices run at a 1.5Mbps data rate to allow cheap electronics and cabling to be used. It simply doesn't need more.

You should always make sure your mouse has the entire USB controller for itself to use, just to eliminate other devices as a possible cause, and make sure you use the latest drivers for everything, try PS/2 if you want to, you never know, but i dont think it's the cause of your problem.

I think the reason you're getting mouse lag only in games is because it's somehow taking long for the cpu to create a frame and for your graphics card to render it. Somehow this can happen even if you don't have a low framerate, it's a common problem. Things you can do is turn off vsync and switch to a different renderer, from opengl to d3d or vice versa if it's possible.

Give us a bit more info here, which games exactly, does it happen in all games, when did it start? Etc etc.

Well its a brand spankin new computer, so it shouldn't have cpu problems, ive only played 2 games, day of defeat: source and Hidden-Source. The mouse seems to have problems in both.

Edit: There is no option, to change from open gl to d3d in day of defeat, any ways of going about doing this?

Edit: The mouse has never worked and DX is up to date.

Do your games run smooth?

Have you tried using hardware cursors?

Turn mouse smoothing off.

Google the game and the "mouse lag" keywords, see if there is anything specific you can do to optimise/fix the problem.

I hope your have the mouse sensitivity in your game options menuís on slightly, so you can actually give your mouse room to work/move in, if its off like set to zero - it may not move in game at all, but only on the menu of your desktop, probably something really stupid effecting it BS, I suggest you fiddle with the options of the games your playing, (there mouse options) at least give it 2.0 if its thievery to let it move, I don't have an mx518 so lawl good luck, I know I wouldn't of brought it, more up to date stuff out there.

like i said, if you are fine with a fer microseconds lower response time, just use the USB>PS/2 converter and shove it in the mouse port...

Mach, hardware cursors as far as i'm aware refer to the (invisible) graphical cursor used to draw screens in graphical 2d modes. I've never seen it as a user-configurable setting with such a name, however.
If i'm wrong, please tell me where you've seen it and what exactly it's supposed to do, i'd very much like to know.

Bulletstopper, try some of the things recommended in this thread, and try some other games using engines other than source. You need to determine the cause of the problem by the process of elimination, before you can start thinking about fixing it.

I'm pretty sure your actual mouse is not your problem, mouselag usually happens when there are a significant number of frames in-transit, so to speak, which causes a delay between the time your CPU starts working on a frame, to the time it's done rendering and displayed on your screen. That's why turning off rendering things such as VSync and also Triple Buffering that store frames in memory before displaying them, help counter the problem.

Pest : I was churning out ideas for BS to try, sometimes in hardware support the biggest frustration is not knowing what to do next. Hardware cursors may not indeed have anything at all to do with the problem.

Anyway seems he sorted it without realising how... just like I managed to boost the speed of my ATI 9600 Pro last night without realising how.
