Help please! Multiple problems

[UnholyWon]

When I use the wand of ooze, Dragon Breath acid, it is pixelled to hell. I have no idea what is causing this or how to fix it.

Also I've been having strange lag that literally freezes me 15 to 30 seconds, making it incredibly hard to quest or be anywhere near effective.

Any suggestions would be welcomed.

I'm just confused as to why I'm having a hard time, and I'm frustrated with it.

Mine loooks like that too, no idea why.

Same here. I know of a dragon override that did that to some breath weapons, so I assumed it was because I hadn't deleted that one.

[Snoteye]

Looks like an override or video card driver problem.

[UnholyWon]

I tried the dragon's breath acid on my laptop, and the FX went off without a hitch and looked normal.

If there is an override I need to delete let me know which one it is, please.

[Snoteye]

Remove them all.

[UnholyWon]

It was definately one of the overrides, sadly I don't know which one. :(

[DeliciousOoze]

Hilarious. You really weren't kidding. Must have been a pain to travel with my character with all those green blocks around.

[putrid_plum]

Ugh, override removal is a pain :(

[UnholyWon]

I haven't tried it sense replacing all the overrides, hopefully problem is solved.

Good lord, my system has maybe 1/5th of the horsepower that you're using and I don't have any of those issues.  Definately an override.

Nice rig btw.

Thanks Ix
