Ffxi Screen Is Freezing But Can Still Hear Audio

i multibox 6 characters on one pc for the last 8 years, but recently i've been having crashes more often. they used to happen just overnight while the game was on but i was sleeping, but not its happening even when i'm playing. and whats even more different is one of the characters' video is freezing but the game isnt freezing. they can still move around and i can hear sounds. but the screen is stuck.

which is why i'm guessing the ffxi community is pointing towards the graphics card.

but i dont know jack about tech. they said to update it and uninstall/reinstall, which i did but the problem is still happening. so i was wondering if i need to update the card since i'm playing 6 characters (on a 20+ year old game) on my pc (only 5 years old). or do i just need to adjust some settings in the cards app?

I use DGVoodoo to improve the graphics so it doesnt look like a 20 year old game. many others use it without this problem happening, but i know it may be part of the problem so including a photo of my settings.

I also use a third party program called Windower that allows me to (among other things) play multiple accounts at once, and i talked with the group that runs that program and they were the ones who suggested it was the graphics card.

so i'm basically trying to find out:

A) do i need to tweak something in the graphics card settings

B) do i need to tweak something in the dg voodoo settings

C) A and B
D) do i need a new graphics card

E) quit using DGVoodoo all together

Thanks for any help/info.

UPDATE:

the freeze just happened again, but i just noticed something i didnt notice before because usually the freeze happened in an area i was in for hours. but i had just checked to make sure all my characters weren't frozen, then continued on in the game. a few mins later i went to switch characters and i noticed one of the characters was frozen. BUT the image on screen was from an area i was in an hour prior.

Sounds to me like your gpu is getting long in the tooth. How long since you upgraded?

It seems unlikely to be a software or configuration issue, since nobody else has reported the same in the community. I would also assume failing hardware, but keep in mind that troubleshooting something like this can be extremely tricky. Check system log in eventviewer for any errors that may be tied to your GPU.

If you're the type of person that doesn't log out at night, like most 6boxers, you should also consider that consumer GPUs aren't really designed for 24/7 operation. 5 years running near 24/7 in a standard case with middle of the road cooling is probably end of life. Obviously they can last much longer if kept clean and cool, as in mining rigs.
