[Hopper64]

Using latest windows 64, 20h2, kombustor crashes with the following error. Latest version of kombustor. Any ideas? Thanks.

Do you have something in Kombustor log file (_kombustor_log.txt) ?

I'm still with win10 v2004 but I will update to v20H2 asap.

[Hopper64]

Don't see any specific error in the log file. Tried it again today with the same application error:

Ok, I couldn't resist to test, so I updated my system with latest win10 v20H2.
I tested Kombustor 4.1.7 with a RTX 2070 + latest GeForce 457.30, and everything seems ok, no crash.

I don't have yet a RTX 30 GPU, so one thing you can do is to rename the GPU monitoring plugin, maybe it's the source of the crash. The GPU monitoring plugin is located here:

MSI_Kombustor_FOLDER/plugins/plugin_gxc_gpumon_x64.dll

Just rename it to disable it.

What is your graphics driver?

[Hopper64]

Driver 457.30.

I added a 1 to the front of the file. No change.

Try 457.33 which is from a different driver branch.

457.33 VK456_14-10
457.30 r457_22-3

[Hopper64]

I don't see a hotfix 457.33 driver available. Where would you download that?

[Stefan]

It's not a hotfix, but a dev driver
https://developer.nvidia.com/vulkan-driver

[Hopper64]

So I download that driver  and install over my existing 457.30 regular GeForce driver?

[Stefan]

Yes, should be no problem.
If you don't like a newer driver for whatever reason, you can always quickly roll back via device manager.

[Hopper64]

I downloaded and looked at the installation files. It will change my existing installation including GeForce experience. I would prefer not to do that if possible. Any other ideas? Thanks!

[Stefan]

If you are not in a hurry, you can recheck with the "RTX 3060 Ti" launch driver on December 2nd

[Hopper64]

I'll probably wait on that and report back. I need a water block for this 3090 FTW EVGA card anyway. Hope EK comes out with something soon. Prefer to have it under water to let it really stretch its legs. Thanks!!

[Hopper64]

Just tried new driver 357.51. Still the same error:

There is something I didn't understand: do you manage to launch Kombustor and see the main user interface?
Looks like there is an issue with Vulkan demos. Can you start an OpenGL demo?

[Hopper64]

I do not see the main interface actually. I just see the cursor of the mouse turn and nothing else.

[JeGX]

ok so try to rename the Vulkan plugin to disable it:
{Kombustor folder}/plugins/plugin_gxc_vulkan2_x64.dll

Can you start Kombustor after that change?

[Hopper64]

Yes! That worked. Renaming the vulkan plugin worked. I didn't know there was a new version of Kombustor available. Downloaded that 4.1.8.0 and still had the same issue, but I just placed a (1) in front of the plugin file--- /plugins/1plugin_gxc_vulkan2_x64.dll and all works as intended. Thanks for the help!! 

[JeGX]

Cool!
There must be a bug in my Vulkan code with new RTX 30 series. But I still don't have a RTX 30 card and then I can't reproduce and fix the bug.
