It is a desktop computer. The RX460 was added after my last video card died on me, and the Win10 has been running on it since it first became available.
I bought Unlimited because Wurm Online ran perfectly fine with all default settings. Unlimited has never run for more than 3 minutes. It typically becomes unresponsive around the 15 second mark, but can sometimes run as long as 3 minutes.
It is the regular game, not the beta. It happens both when running my own server, or when connecting to other servers.
I've tried uninstalling, reinstalling, and even moved it to it's own HD. Video card drivers are updated and the only ones on the pc. All others have been removed, registry is clean, etc. I know that java comes prebundled with the steam copy of Unlimited, but otherwise, I only have the 64 bit latest version installed, same as the video card and all other drivers.
It is an older mobo/processor, but otherwise the rest of the machine is new.
I am able to run games like Skyrim (GOTY) and FO3 on ultimate settings, but I haven't even tried on here. I had tried changing all the settings to the minimum, but it didn't help. Honestly, I've tried just about every bit of advice this forum gave before even posting.
I have checked out the load on both the cpu, ram, and graphics card while the game is running and while it's crashing, and there really isn't a reason as far as I can tell. It's not overworking the pc.
As I said, most times the game doesn't even fully crash. It just goes black and or white screen and continues playing music while it tries it's hardest to continue being a program.
Included is a dxdiag report in the spoiler tag.
Thank you for taking the time to try and help.
