ATI Catalyst 8.10 Fixes the Displacement Mapping Bug in OpenGL

Great news! At last, ATI has fixed the displacement mapping bug. Now you can do vertex texture fetching in your vertex shaders with a Radeon! And GPU Caps Viewer is happy:

More information about vertex displacement mapping here: Vertex Displacement Mapping in GLSL Now Available on Radeon!.

You can grab the Catalyst 8.10 BETA from here: Catalyst 8.10 BETA.

I wonder if ATI will write this bugfix in the release notes… Anyway guys, this new release of Catalyst seems to be a great version…

ATI Catalyst 8.10 Beta Graphics Drivers

The upcoming (october 2008 version) Catalyst graphics driver is available in BETA version. You can download the huge archive (~200Mb) here:
Catalyst 8.10 BETA for Vista
Catalyst 8.10 BETA for XP

As soon as the WHQL version is available, I will publish the OpenGL extensions because GPU Caps Viewer told me that Cat8.10 has around 115 extensions

Here are the screenshots of my Radeon HD 4850 and Catalyst 8.10 BETA under XP32:

– GPU: RV710 / 600MHz / 55nm
– Shader Processors: 80
– Texture Units: 8
– ROPs: 4
– Transistors: 242M

Radeon HD 4870 X2: The Fastest Single Slot Graphics Card!

The guys at Rage3D have spent a lot of time to test the Radeon HD 4870 X2 with around 16 different games. The 4870 X2 is based on the the R700 GPU (actually two RV770). And their conclusion is clear: the Radeon HD 4870 X2 is the fastest card at this point in time. They also recommend, if you have the choice, to buy a Radeon HD 4870 X2 than two Radeon HD 4870 in Crossfire. And last point, an important advice is to have a fast, very fast CPU in order to fill the 4870X2’s command buffer (read send enough graphics data to the card).


Good things come in pairs


This test is focused on DirectX 10 and DirectX 9 titles and it’s a pity that Rage3D has not tested the 4870 X2 with OpenGL applications.

ATI Radeon HD 4870 1024Mb Review

This Radeon HD 4870 (RV770 GPU) with 1Gb GDDR5 of graphics memory can be seen as the answer to NVIDIA GeForce GTX 260 Core 216 (see here and here). And from the tests, the Radeon HD 4870 1Gb is a little faster than a regular GeForce GTX 260 Core 216 but has to compete fiercely with the pre-overcloked versions of the GTX 260 Core 216 (like BFG and eVGA).

TimeCube: a Cool Useless OpenGL Demo…

TimeCube is an OpenGL demo that renders a small rotating cube, displaying the current date and time, directly on your desktop. Common effects are used: specular highlights (trop fort les gars!!!!), realtime bump mapping (le truc qui tue!!!) and cube map reflections (là ça explose tout!).

You can grab this software gadget here: TimeCube Demo.

The demo does not eat cpu cycles so you can leave it runing somewhere in your desktop….

eVGA GeForce GTX 280 HC16 Hydro Copper Review

For those that already have a water cooling system, this EVGA’s product might be interesting. This GeForce GTX 280 is overclocked (core is overclocked by 89MHz (602MHz to 691MHz), memory by 108MHz (reference 1107MHz to 1215MHz) and the shaders are up from 1296MHz to 1458MHz) and comes with a large water-cooling block, the complete card keeping a nice single slot design.


From Guru3D, this is top-notch product. The most important thing is the temperatures are very nice. But even if the GeForce GTX 280 remains the fastest single GPU based product on this planet, ATI products just offer more value for the money. But if you need features such as CUDA or PhysX, so this card is the right choice. But the US$600.- price of this simple bundle is not really cool…

EVGA GeForce GTX 260 Core 216 Superclocked Review

EVGA’s GeForce GTX 260 Core 216 is the new version of the GeForce GTX 260. This version adds 24 shader processors to the existing 192 (192+24=216).

The Geforce GTX 260 core 216 is in fact a GeForce GTX 280, with a small chunk of memory missing, and one shader cluster with 24 shader cores disabled. Other then that, there is just no difference whatsoever.

So in general the Core 216 edition cards offer a small small step in performance over the regular GTX 260 products, but the faster clocked Core 216 products, darn it, that’s where value starts kicking in for sure.
