Monster Hunter Frontier is a DirectX 9 benchmark and is derived from the full game.

You can grab it here: Monster Hunter Benchmark DOWNLOAD

With a core2duo E8400 / 2Gb DDR3 1333 / Radeon HD 3870 Catalyst 8.8 WinXP 32, I get the score of 6425 points.

Gainward Expertool ATI v4.0 enables Radeon HD 4850 / HD 4870 fan and clocks control without CCC or BIOS modification. I just tested it and it works fine also with other Radeon like the Radeon HD 3870.

[Geeks3D-Test] ATI Catalyst 8.8 vs 8.7: OpenGL Performance Drop

Catalyst 8.8 graphics drivers have been released few days ago, and today, or better this evening I’ve done some tests with oZone3D.Net OpenGL Benchmarks and a Radeon HD 3870 (stock clocks). I also used Lightsmark 2008 in order to have another OpenGL 2.0 application to confirm oZone3D.Net OpenGL benchmarks.

Here are the results, rather unexpected

	Catalyst 8.7	Catalyst 8.8	Diff
FurMark 1280×1024	3100	3229	+4%
FluidMark 1280×1024	954	937	-1.8%
Soft Shadows Branching OFF	3384	2590	-23%
Soft Shadows Branching ON	4088	2993	-26%
Surface Deformer	13526	10332	-23%
Lightsmark 2008	391	376	-4%
TOTAL Sum	25443	20457	-18%

System Configuration: Core 2 Duo E8400 default clock, motherboard EVGA 790i Ultra SLI, 2Gb DDR3 1333, HIS Radeon HD 3870 default clocks, Catalyst 8.8 XP32, Windows XP SP2 32-bit.

Global Performance Drop: 18%. OpenGL performance tumbled by around 26% in dynamic branching (soft shadows), around 23% in vertex processing (surface deformer) and around 4% in Lightsmark 2008. Only FurMark takes advantage of Catalyst 8.8 with a little 4% of performance boost. FurMark makes an intensive use of texture fetching and blending (ROPs) and maybe ATI has improved something in this part of Catalyst. But as said hereafter, Expreview has noticed a performance drop with a Radeon HD 4850 and FurMark. I don’t have such a radeon and then I can’t confirm this last result but FurMark score is somewhat weird…

Expreview on his side, has tested the Catalyst 8.8 with an ATI Radeon HD 4850 and compared to Catalyst 8.7, the new driver boosts the performance in games. If you have a Radeon HD 4850, Expreview recommends you update to Catalyst 8.8. But if you look at the results more seriously, you can notice that scores are boosted mainly for DirectX 10 titles. In other OpenGL or DirectX 9 titles, there is no or a little boost only. And with FurMark, Expreview has the same kind of performance drop I had with the HD 3870.

TweakTown in his Catalyst 8.8 review has also experienced a severe OpenGL performance drop with Radeon HD 3870 and Cinebench, the OpenGL benchmark derived from Cinema 4D. The Radeon HD 4870 has a drop too but less important.

Conclusion: for OpenGL applications that are performance focused, it’s better to not use Catalyst 8.8. In some cases, Catalyst 8.8 brings a little boost only and in other cases, a dramatic drop is noticed.

If you have some interesting results with OpenGL applications, do no hesitate to post a comment!

Sapphire ATI Radeon HD3870 Ultimate

The Sapphire Radeon HD3870 Ultimate features a fanless heatsink for cooling. As expected, the card is bigger than a dual-slot cooling solution, but it’s well worth the sacrifice for passive cooling.
