suddenly laggy with Vista

[Pico18]

My father has been playing Defcon for a million years (exaggeration) on this computer and all of a sudden, some weeks ago it decides to be laggy. I have Windows Vista, and as far as I can tell, nothing has changed recently to warrant such a thing. It's more the mouse than the actual game, though the game has slowed also. He can barely get anywhere the way the mouse moves, all jumpy and awful. I've tried changing the bitrate and the graphics, windowing it and resolution.. anything I could think of, but nothing changed anything.

Can anyone relate? Can anyone help? X3
Thanks!

Anybody? Please, come on. He's getting awful whiny and it's making me feel guilty. XD C'mon gimmie a hand. *begs*

Restarted the computer lately? Hardware specs?

Yeah I shutdown every night. I've reinstalled the game a few times, too. Nothing I do changes anything.

De hardware specs are where they should be, also.
Plus that, the games worked since we got it, couple few years ago. Two moths ago it decides to not work. *shrugs*

In order to help you, you need to tell us as much as possible. We aren't mind readers so what you don't tell us we won't know and it helps to know:

• Your hardware.
• Defcon version.
• Defcon type. Steam or non-Steam?
• Graphics driver version.
• If you've installed any software likely to affect Defcon i.e. programs that run in the background or persistently.

You may feel it's irrelevant information but something has clearly changed lately. If something hadn't changed, you wouldn't have a problem. Windows releases patch updates every month and your anti-virus should update frequently so your system should have changed over the last few years, this may have had an effect on performance.

In regards to hardware:

After that we need to know your system specs. You can find all these by running dxdiag ([Go to Start and click 'Run'.
Type in: dxdiag]). The System tab lists what information we need; here's a list of what is best to add:

• Defcon type (Steam or standalone)
• Operating System
• Processor
• Memory
• DirectX version

On the Display tab lists other information that you should include:

• Under Device:
  
  • Chip Type
  • Approx. Total Memory
• Under Drivers:
  
  • Main Driver
  • Version
  • Date

On the Sound 1 tab lists the final bits of information you should include:

• Under Device
  
  • Name
• Under Drivers
  
  • Name
  • Version
  • Date

If you are not sure, include the whole dxdiag output (Click the Save All Information, and open the created file, and paste it in your post)

'Read me first before submitting a bug report!' also suggests before reporting performance issues that you update your graphics and sound drivers, did you try that? After trying that it also suggests "Setting SoundHW3D to 0 and SoundDSP to 0", did you try that?
