There's nothing wrong with the results online, but you must remember that they generally stick to standard settings and commonly tested games. Almost every GF100 review had Far Cry 2, Call of Duty 6, Stalker CoP and a few synthetic tessellation benchmarks. Almost every reviewer sticks to 0xAA or 4xAA too. I used Far Cry 2 as well and I saw a large performance gain, just like mainstream reviewers.
Obviously nVidias drivers are currently optimized for such predictable situations, so the cards paint a very good picture with mainstream reviews.
But I tested
36 different games of varying ages using varying AA and TrAA levels, and thats when the performance issues started appearing. The GTX285 has gold standard drivers, plain and simple. On that card 197.13 still generated a performance gain of about 5% across the board for me, which is simply amazing considering how long the GT200 chip has been around.
And thats why the GTX470 currently cannot compete with a GTX285. In cherry-picked scenarios its faster, but if you widen the net its the same speed or slower than a GTX285 overall.
Furthermore:
- Used an i5 750 CPU.
- I tested both Windows XP and Windows 7, and in most cases saw similar results.
- My GPU clocks were working properly.
- It was not a super-sampling issue. I know exactly how SSAA works, and thats why I know it wasnt a factor. It cant be a factor for Toyota either since the 256 drivers require super-sampling to be explicitly set.
To put it bluntly, Toyotas results dont surprise me at all, and Id say his CPU has little to nothing to do with it. These are driver issues, plain and simple. Im tempted to pick up a GTX480 to demonstrate a performance gain over the GTX470.
As for the 25%-30% comment, thats a noticeable performance gain when its actually in effect. I saw that kind of performance gain when going from a GTX260+ to a GTX285 and it definitely impacts actual gameplay.
