[ACTU] Le jeu sous Vista : test des drivers NVidia et ATI/AMD

Et ben c'est pas folichon par rapport à XP + aucun support des jeux OpenGL....

Citation: Conclusions Judging from what we have seen thus far, the gaming performance available to enthusiasts is somewhat mixed on Windows Vista. Both NVIDIA and AMD have some areas where their cards perform well and others where they do not and features from XP to Vista haven't translated over quickly either. Performance First looking at the performance of the Forceware 100.54 driver and the NVIDIA GeForce 8800 GTX and 7900 GTX, I very obviously was let down by the Windows Vista gaming experience. I didnt' get to test as many games as I would have liked for this review due to the tight time restraints put on me by the driver availability, but in the games that we did go through only one of them was what I would call a "win" for NVIDIA: FEAR. In FEAR the performance under Windows Vista was nearly at the same levels we had seen in Windows XP and didn't present any issues in compatibility or stability. I guess I'd have to say that Call of Duty 2 performance was also acceptable even though we had to use control panel AA settings instead of in-game AA settings. The experience I had with AMD's first Vista driver was much more positive. Most of the games I tested showed to be on very close performance levels to those we expected from Windows XP; the exceptions here were FEAR and Prey. Obviously with Prey not loading at all on our Vista test system, that presents a BIG problem but AMD is confident they'll find the problem and fix it fast. I'll let you know when that happens. FEAR performance was let down as well, though with the maximum FPS at 46 across the board in our tests, chances are this can be fixed pretty easily as well. Overall, in terms of performance, NVIDIA is lucky that they have the GeForce 8800 series of cards available and AMD's R600 is still behind closed doors. The raw power of the G80 core is able to keep the 8800 GTX as our performance leader in Windows Vista even with the mentioned performance problems when compared to the AMD's flagship ATI X1950 XTX card. Driver Features As mentioned on the first pages of this article, the driver features comparison between ATI and NVIDIA is pretty dramatic. AMD was able to get the ATI Catalyst 7.1 driver to not only be fully functional, but added some new features like Blu-ray and HD-DVD support and a new control center that loads faster and has better previewing capability. They full admitted that OpenGL performance was going to be lower than we expected in Windows XP (though not working wasn't in the books!) but with CrossFire working in the exact same way as it did under Windows XP the AMD ATI Catalyst driver seemed pretty refined and ready for the spotlight. NVIDIA's Forceware 100.54 driver on the other hand was more or less a mess. SLI support was not enabled and as of 10am on the 30th, the day Vista was released, it still wasn't ready. That is a very big let down for any enthusiast gamers who put their stock in NVIDIA technology with their hard earned dough. TV output and HDMI support is pretty much a wash here and several bugs stand out as making this driver revision seem rushed and hacked together. As I complained about in the earlier segments, how can a driver for a product in development for 4 years (G80) for an OS in development for what seems like forever, NOT be ready on launch day? Final Thoughts It may seem like my testing with gaming performance in Vista all resulted in a feeling of doom (nope, no OpenGL support!) and gloom, but don't let that scare you off just yet. I think we all expected there to be some initial growing pains with the Vista operating system and PC gaming simply because of the dramatic shift in driver technology that had to take place; I just don't think we expected it to be this bad. AMD's driver development team is definitely a leap ahead of NVIDIA's as the initial release ATI Catalyst driver offered a gaming experience much closer to that of Windows XP in the new Vista OS than NVIDIA's initial Forceware release. This may change as driver revisions are updated through the comings months, so we'll definitely be keeping an eye on both companies progress. For now, gamers that were interested in running off to get a copy of Windows Vista, I'd caution you to take a minute and contemplate. Gaming under Vista is definitely possible and if you're comfortable with some slight performance drops for now while taking advantage of Vista's other new features, then a move to Vista sooner rather than later should be considered. If gaming and gaming performance is your only metric for your PC, then I'd definitely hold out on upgrading until AMD and NVIDIA have their software perfected.
