Ultra does not work with AMD RX6800M, AMD RX6900 XT

[Canardia]

I tested the Benchmarks and neither my AMD RX6800M or my friend's AMD RX6900 XT would start the Ultra benchmarks.

[Josh]

Besides the obvious driver update, it is also possible to enable Vulkan debugging by adding the validation layer in Ultra.json, but you don't need to do this unless you are just curious about it.

I think I know what my next GPU will be.

[reepblue]

But it worked on other AMD cards though before the engine went public. Not sure why that is...

[Canardia]

I'm pretty sure Josh will find a clue why the previous generation high end AMD Radeon cards like RX6900 XT won't work with Ultra,
and I'm also sure he will make them work with Ultra performance.
I can't wait for Godot 4 fall out of the competence.
Then I can focus on a Newton vs Bullet challenge, like I did in Leadwerks.
My current testbed consists of 10000 physics cubes which perform quite well (700 FPS).

[Josh]

I know you like Bullet, but there's also a Newton 4, which is quite a lot faster. I started implementing it but decided to stick with Newton 3 because I knew I could deliver reliable physics with it. 

There's also a hidden implementation of Box2D in the engine, but I don't think it is usable yet.

If you're interested I can abstract away the physics engine so the end user (you) can insert your own physics library and still use the same engine commands.

[Josh]

I assume this issue this persists, and that installing the VulkanSDK does not produce any validation errors?

[reepblue]

This might be related. I just set up a machine today for testing and I can confirm that when Ultra Engine on release will crash when creating the framebuffer. 

In debug mode, the project works fine but we have artificing. 

The Vulkan SDK isn't really helpful. No popups or anything (Ignore the material loading messages, this is an issue I've discovered with my git server. 🤪)

Hope this helps.

What GPU that be?

[IceBurger]

I have an rx6800xt if it's needed

Ok lol, you probably have my address on file from purchases.

I come in house tonight. I pick good time

This was my RX480. 

[Josh]

I found a 6600 at Best Buy, and those are probably pretty close to the 6800 so I can get that and test it later this week.

What's important is you now in your hand have a AMD GPU! Hold on to it. Although players choose Nvidia 9 times out of 10 for Windows Gaming PCs, the tide might turn AMD for more affordable card for gaming. Plus, AMD GPUs are by far a popular choice for Linux users. Plus, the Steam Deck uses and AMD APU. 

[Josh]

My R9 280 is no longer receiving driver updates and the last driver only supports Vulkan 1.2...

[reepblue]

Still picking up the 6600? I thought that was the plan?

[Josh]

Yes, I just haven't gotten it yet.

[Josh]

I have a 6600 now. Editor runs fine in debug mode but crashes in release mode with no messages...

[Josh]

This is very bad.

If I add a Print statement in the rendering thread the program works fine. If I replace the Print statement with Sleep(1000) then it crashes with no explanation.

The debug build runs fine with no validation errors.

[Josh]

I have some clues and I am investigating...

[Josh]

Reported to AMD here:
https://community.amd.com/t5/newcomers-start-here/radeon-6000-series-failing-to-run-vulkan-application-developer/td-p/636173

[reepblue]

I'm sure this is the exact reason affecting other AMD cards like my RX 480.

[Thirsty Panther]

Interested to see how this works out.

I'm looking at building  new PC in the near future and AMD cards seem  to provide the best bang for buck but I'm happy to pay a little extra for a GPU that plays nicely with Ultra Engine.
