Here's a real stumper. I just upgraded from an nVidia 8800GTX to an AMD Radeon HD4870 video card. Nifskope ran flawlessly using the nVidia but has developed an annoying problem while using the Radeon. The video card upgrade is the only thing I've done to the system at all.
When I open a nif file and the image is displayed in the render window, I cannot click on any portion of the actual image or the application crashes with a Windows error dialogue. The best I've been able to capture from the crashes is this:
"Faulting application nifskope.exe, version 0.0.0.0, faulting module unknown, version 0.0.0.0, fault address 0x0698df0f."
The fault address is random though. This happens with every nif file so far I've tried it with. I cannot select anything by using the render window. However, I am able to navigate the entire node tree on the left and manipulate the data as normal. Even including removing blocks and such from the image. However once I've clicked there, I can no longer click on the render window at all for any reason, in any part of it. The problem affected Nifskope version 1.0.12 so I came by to check for upgrades, and sure enough you have 1.0.14 now. I've installed that and the problem still exists.
I'm able to work around the problem for now but it's definitely slowed my ability to work with the program in a bad way.
I'm not sure how much it will help, but here's a rundown of my system specs:
AMD Phenom 9850 2.5Ghz
Sapphire Radeon HD4870 1GB (single, not an X2, no crossfire)
Catalyst 8.8 release drivers downloaded from game.amd.com
4GB Corsair high performance RAM
If you need anything more, let me know. I realize it's pretty vague and randomish but I'm not really sure what else to dig up right now.
