The Radeon X video cards, that included a R, were released with a delay of several months because ATI engineers discovered a bug within the GPU in a very late stage of the development. This generation has support for all recent memory types, including GDDR4. This site works best with JavaScript enabled. Do you want to post some of these broken shaders for us to look at? The card was launched on August 23, Many thanks for your time and help in advance. At the end of the pipeline, the texture addressing processors are now decoupled from pixel shader, so any unused texturing units can be dynamically allocated to pixels that need more texture layers.

So I don’t even know where to start.

This site works best with JavaScript enabled. Not only are they fully Shader Model 3 capable, but ATI introduced some innovative advancements in shader threading that can greatly improve the efficiency of the shader units.

RV, for example, atu two internal bit buses instead. I uploaded a new version that fixes all GL errors, same link as above, but the appearance is the same. Here’s what it should look like. This can usually be fixed by updating the video card drivers. A compatible HDCP display is also needed for this.

You haven’t mentioned whether you tried the current amd. I followed your suggestion, installed the driver pack using the options below:.

Can you post a link to your app? This series is the budget solution of the X series and is based on the RV core. Radeon HD Series.


After searching high and low without any luck, I wonder if one of you experts can advise if there is any display driver that is compatible with my graphic card but also with OpenGL support, before I invest in a new laptop?

A lot of users will understandably be reluctant to go back that far unless they have to.

The laptop is fully functional, enough for what I need. When one of the shader quads becomes idle, due to a completion of a task or waiting for other data, the dispatch engine will assign the quad with another task to do in the meantime, with the overall result being a greater utilization of the shader units, theoretically.

OMG you saved my life!!!! Then I tried testing with an ATI Using my Desktop is a hassle so i decided for search for a solution. I followed your suggestion, installed the driver pack using the options below: There’s some EMBM on the walls and floor, but it is hard to see in a still shot because the scene is not very high contrast: With chips such as RV and R, where the number of shader units per pipeline triples, the efficiency of pixel shading drops off slightly because these shaders still have the same level of threading resources as the less endowed RV and R This tool uses JavaScript and much of it will not work correctly without it enabled.

Basically the chip can spread out memory requests faster and more directly to the RAM chips. Like its predecessor X, the R chip carries 4 “quads” 4 pipelines eachwhich means it has similar texturing capability if at the same clock speed as its ancestor, and the NVIDIA series. Rollback Post to Revision RollBack. Have you guys experienced anything like this? The chip’s single “quad” has 3 pixel shader processors per pipeline, similar to the design of R’s 4 quads.

Do the ATI driver report any problems when compiling – or is it only runtime issues? This design allows memory accesses to be far quicker though lower latency by virtue of the smaller distance the signals need to move through the GPU, and by increasing the number of banks per DRAM.

I have a long way to go to figure out everything I need to know about technical computer stuff. The chips have 4 texture units4 ROPs4 pixel shadersand 2 vertex shaderssimilar to the older X – X cards. X was not behind schedule, and was always planned as the “spring refresh” chip. Can you give me the exact model number of the laptop?

But everything compiles fine.
