Re: Old ATI DX9 Tessellation SDK
By coincidence, I pinged internally the day before you posted this, but I still haven't heard. I'm going to ramp up the heat a bit. I don't know that we can provide what you want, but at least we can...

Re: Old ATI DX9 Tessellation SDK
And the answer is in: it is not available. Just FYI - for tools we keep the previous version readily available. Sometimes we'll have a slightly deeper stack, but typically you can go one version back....

With luck, one of the engineers can take a look at this next week. We have it on the radar. Just making sure everyone knows, silence != we're ignoring you. We can't get to everything, and some of what...

Thank you very much for your reply. It is a pity that this sample is not saved in your archive. But maybe you have contact details for the person who did it? I would try to contact him.

TressFX: First rendering pass is 5x slower than dx11 counterpart
Hi, Again about TressFX in OpenGL : the full OpenGL version (ie without OpenCL) works and display similar output as DX11 SDK.However I have poor performance with the first pass (which fills per pixel...

Hi, Your shader looks fine. My guess is that we're hitting some kind of performance issue related to incrementing the atomic counter. If everything needed to run the sample is in the GitHub repo you...

Thanks for your feedback, I included source of all deps Inside the repo, it only requires CMake to generate the visual studio solution. (which should be located in a subfolder inside YAGF/ folder, I...

Hi, I need for my application that every drawing produce at least one pixel output (even if this is an empty triangle = 3 identical points). NVidia have an extension (GL_NV_conservative_raster) to...

Hi Tof, Some of our hardware can support functionality similar to that in the NVIDIA extension you mention, but we are currently not shipping an extension of our own. We will likely hold off until we...

Thanks for your answer. In fact, It was 3 identical points in final pixel coordinates, but 3 different points in vec(x,y,z).I need this because I must not loose any data information when displaying...

Re: Violation access with cl_event from GLsync usage
Some additional information : With Catalyst 15.3 the issue still appears, but if I run it with CodeXL debugger I don't have crash. However "output" console in VS 2013 get spammed with : CodeXL - Debug...

For obvious reasons, we can't answer a question about when something is going to show up. Particularly in this case because it is an open standard, and we're dependent not only on our own engineering,...

Thanks for the report. I have passed that on to the engineers. If they have questions or suggestions, they'll jump into the thread.
