Na Xbitu se pojavio zanimljiva usporedba DX 10 grafa u DX 10 igrama.
Obrađene su sve kategorije od 2400 XT i 8500 GT u najnižem segmentu, 2600 XT GDDR4 i 8600 GTS u srednjem i 2900 XT sa 512MB/1GB i GTS 320/640 i na kraju GTX u najačoj klasi.
Conclusion
Summing everything up, we have to say that the support of DirectX 10 in both software and hardware is in fact merely nominal.
None of the tested games can boast much higher visual quality in comparison with the DirectX 9 applications while the use of DirectX 10 lowers the frame rate. We guess the only lucky example of a DirectX 10 game is Call of Juarez DX10, but largely due to its initially beautiful DirectX 9 visuals.
Using a wide range of test modes we could not achieve a high frame rate at high quality of game visuals, so we don’t think the speed will be acceptable even at the lowest settings.
Talking about the tested graphics cards, we can note the following:
Modern high-end graphics cards may have good performance in today’s games, but they do not look future-proof considering the results of available DirectX 10 tests.
Modern mainstream cards are not a good choice for a devoted gamer and are not future-proof at all.
Modern entry-level products from AMD and Nvidia are hopelessly slow in DirectX 10 applications and can only be recommended for viewing demos from the GPU developers.
But if you decide to buy a DirectX 10 card today realizing that you’ll need another 3D card to play games scheduled for 2008, this test session has shown that:
Despite its unassuming performance in DirectX 9 benchmarks, the ATI Radeon HD 2900 XT is capable of beating the Nvidia GeForce 8800 GTX, which is much more expensive, in DirectX 10 applications provided that the Catalyst driver has game-specific optimizations. Of course, Nvidia’s ForceWare driver has to “know” the particular game to run it at a high speed, too.
The ATI Radeon HD 2600 XT and HD 2400 XT are kind of DirectX 10 kings in their respective price categories. However, these cards often prove to be slower than Nvidia’s GeForce 8 in the more important DirectX 9 applications.
The ATI Radeon HD 2000 architecture features the most advanced implementation of DirectX 10 today.
Performance of both ATI Radeon HD 2000 and Nvidia GeForce 8 is fully dependent on drivers, therefore, it is nearly unpredictable which graphics card will eventually become better DirectX 10 performer.
GPU developers have made a point of releasing two product families based on the same graphics architecture to guarantee a lifecycle of 1-2 years since the announcement. If this trend continues, we’ll see new series of DirectX 10 graphics cards from the leading developers this fall. However, these new series won’t differ much from the current ones architecturally, and so we don’t expect them to bring about any performance breakthroughs
