A ton of things in the scripting and physics parts of the engine are directly tied to vsync. There’s a very good reason it’s not a user-exposed option. I don’t want AMD to forget about VLIW, but right now, GCN needs so much work it is nearly incomprehensible. Not that GCN isn’t a good performer, but there are a lot of bugs and a ton of performance potential to be tapped, both by AMD and by game developers.
You still haven’t commented on why you’re avoiding games with tessellation. The 7870 outperforms the 7970 in that test because performance there is gated by triangle setup rate, and Tahiti and Pitcairn share the same front-end hardware. The Pitcairn card has a higher clock rate, ergo, higher throughput.
Each animation has startup, active and recovery phases, and these are equally applicable to a game like SC2 or LoL. Its nice u have collected data to compare and contrast with. Other websites will have a hard time showing a difference or at least catching up to you guys. Now you can add more variables to yor testing like memory speed, different resolutions, cpu and gpu overclock, ssd vs hardrive etc…heck maybe even a last generation graphics benchmark test…. like maybe a Radeon HD 6970 vs. Gtx 570 would be neat. Anyway, bottom line, its a good thing that TR is around to keep these people on their toes to minimize the repeat of such issues in future, ensuring better PC gaming experiences for all . This looks to me like one of AMD’s competing driver development groups had a temporary brain fart and messed something up that was already working more or less fine in a recent driver.
It seems to be a “feature” of VGA drivers in general and manufacturer-specific variants in particular. There’s actually quite a number of third party programs that make their living off of cleaning up the mess left by AMD drivers. Most people recommend completely uninstalling the old drivers and running some sort of driver cleaner before installing new drivers. They won’t benefit from things specifically aimed at GCN, but their performance is already rather closer to their theoretical capabilities. Are these driver optimisations specific to the 7950 or do other models benefit?
Also what about older 5 and 6 series cards, do they benefit? The Borderlands 2 game engine does not support triple buffering, so if you run with VSync on you’d better use settings in the game that gives you a more or less constant 60fps.
And yes the Intel chips are better at gaming too… but really gaming is a very small slice of the market compared to the enterprise world. To see that “time spent beyond 50 ms” go from a few dozen to zero is an excellent sign. They obviously have good people working on those drivers to get such a turnaround and do it quickly. conexant driver I don’t have any numbers to verify this or back it up, but because those resolutions have less information to render, ALL frame times should be lower, spikes and all. Reducing other settings should also lower frame times. To an extent all games are based on framerate, It’s just emphasized more in fighting games.
Otherwise the next step below 60 will be 30 with no in-between. Any modern game supports triple buffering and has VSync on by default today, but Borderlands 2 was a hack. Wow remind me never to get an AMD card, I was getting better performance on my single 470 GTX and my new 680 GTX is out of this world. Also AMD makes some very excellent products… the only issue is that lately it seems like either Intel or NVidia has a ever so slightly better product out. For productivity tasks they easily hold their own against even the Intel i7’s in terms of raw performance. But the Intels are just as fast, for almost the same price, or not much more, and consume half the power.
I still use integrated audio instead of the audio on the video card does that make the vid worthless. the cards still work fine, in the 4870’s case they were an example of a very long lived product that was inexpensive, performed well on release and aged very well over time. as an example after a several year hiatus I’m currently playing all of the Mechwarrior 4 games, Vengeance, Black Knight, Mercenaries. It was stated on the last page that the memory manager rewrite that should come in a few weeks will help out all, or at least most, DX10/DX11 games in terms of latency. That means no reliance on special, game specific profiles. Well even if they did this just to unrustle TR’s jimmies, they have still reproduced the problem on their own and managed to fix it. It remains to be seen if they will apply the things they learned doing this to other games or their testing in general, but it’s a step in the right direction anyway.
