Hi there, I'm evaluating Stereoplayer which works fine except for this issue. However, I'm not convinced this is an AMD driver problem, because the issue isn't there (and has never been there) with any...
View ArticleRe: Can mantle partition a GPU for two workloads?
Hi, Mantle does not allow you to have multiple graphics queues with different priorities, however if one of your jobs (probably the real time task) can be done using compute only, then you could use...

In amd driver, if developers do not specify the layout location through either glBindAttribLocation() or write "layout (location=index)" in shader source, driver will default set color attribute...

Thank you, that answers my question. I'll consider reimplemetation with asynchronous compute queue.

I've checked TMT and as I've mentioned in a previous post it uses an undocumented API. It seems to be hardware-overlay-based because when taking a screenshot you only see the chromakey color instead of...

Hi, any news about a public, or at least a more open, Mantle SDK access? I was able to get the DX12 EAP as single individual, however Mantle SDK is still in closed beta and for software house companies...

Here's a wild guess, shooting from the hip... This has nothing to do with SSBO. It looks from your mention of glUseProgramStages that you're using SSO. In that case, you're required to declare...

Hi Graham !Thanks for your reply and your great work. But i still cannot to realise what i need to do. gl_PerVertex used as input in geometry shader, not fragment. If i try to declare gl_PerVertex in...

The interface is between pipeline stages, fragment shader would not have an output interface because there is no exposed pipeline stage after the fragment shader. With that said the fragment shader...

It's OK but i cannot declare gl_PerVertex for fragment shader as it's not a fragment shader input. If i try to do it then i'm getting an error as i described above.
