View Full Version : New Nvidia driver will fix over optimisation

Seen on the inquirer and quoted here bout the new fix in 78.03

NVIDIA WAS very fast to react to a story we pixellated yesterday. We wrote here about Nvidia's over optimisation. Well, as expected Nvidia said it's a bug and it could not be fixed by changing to high quality driver setting, which was the case with Geforce 6 series cards.

Nvidia claims that a new beta driver, version 78.03, will fix the problem, and the driver is already with reviewers. Nvidia will post this driver later at its nzone.com website but after it gets feedback from the reviewers. Don't you get the feeling sometimes that reviewers are the final unpaid quality check for these hardware manufacturers, but without the big salaries?

You can expect a few per cent performance decrease but it won't be even close to 30 per cent. The decrease will occur in the high quality mode, of course. Nvidia claims that it has nothing to fight, it's just a bug and nothing more.

The 78.03 driver will also fix a separate bug reported by some users. Some of them complained that certain application profile settings didnít work. Nvidia addressed this and fixed it in its upcoming drivers. Some of our colleagues will sure provide you with some tests as we are set to be away for a gaming event in London.

Or will it a new hoax with older fps speeds???

YES! i knew they were fixing shimmering but not the over optimization. i guess this means if we change setting to 'high quality' we will finally get ati quality aa/af! :D

They had better fix the MPEG2 hardware acceleration problems in the 77.xx series (affecting at least FX cards).

These are looking like my beloved 67.66 set, from what I've read, yet with triple buffering and OpenGL 2.0 support, which are the only reasons I didn't just stick with the older drivers.

Oh, almost forgot. I hope they, when fiddling with the profiler, manage to fix the Far Cry and NFSU 2 profiles so that the games run properly without using third party software or renaming the exes. No biggy, but I like things to work correctly through the official channels, as many users don't know the workarounds.

Oh man...the 66.77's. Best. Driver.Ever.

All very good, but I'm dreading the drop in performance!! :eek:

What performance drop?

this reminds of the bug several versions ago (way back).. where everyone loved the increased speed but in the end it turned out that something like specular lighting was broken..


but i think everyone will agree, IQ over Performance, or the very least let the user be able to disable the optimizations that compromise IQ for performance..

Nope been here 10 times a day and had good eyes.
Only those threads seems be placed on another spot that actually under nvidia drivers topic.

That SLI profile bug isn't fixed with 78.01...highly doubt it'll be fixed with 78.03. The fact that both are old games and only non-SLI systems are affected = not high priority, I guess.

I thought the over optimization was the cause of shimmering therefore isn't it the same fix or do I have something else to look forward to?

Nvidia claims that it wasn't a new optimization. It was a simple BUG!

The performance loss of 1-4% tells me that Nvidia is telling the truth (1-4% was possible a few times before by any new driver)

Did the Inquirer refer to themselves as quality just then?

Sure one day before, they quoted bout this thread:

Germans claim Nvidia caught "over optimising"

WE CALL IT optimisation these days, but what do you call it when a firm over optimises? We used to call it something different in the days of the NV30, when Nvidia had to do something to make its chip work better and do better in benchmarks but to our surprise it seems to have done it again. The chaps from 3D Center, a very talented in-depth site, spotted and tested and proved that Nvidia is using a lower anisotropic filtering quality than any other card available.

Those guys noticed a texture shimmering problem when you are using normal driver settings. This was the case with NV40 cards but you could resolve this flickering by using high quality driver settings. This won't work on G70 based cards, so the guys well known for its thorough benchmarks went digging a little deeper into the chip.

It turns out that Nvidia is not doing anisotropic filtering the way it should and that the picture quality is the one to suffer. You will get the shimmering effect on your textures whenever you are using Geforce 7800GTX cards but you won't see this using Radeon cards.

The guys claimed that all NV40 and G70 cards will suffer from the same flickering problem and that these cards have "by far worse AF quality". They also add that Nvidia got the flickering because it was using general under sampling and as a result is getting the flickers. It's interesting to note that older Geforce 5800 Ultra won't suffer from this, just the new cards that 6800 or 7800 based.

Another German web site Computerbase , went a step further. It made a custom driver by changing the inf, where the driver could not recognise 7800GTX and use its optimisations. The card was listed as unknown but was working just fine. But when the guys went testing they noticed a massive performance drop when using those drivers, close to 30 percent and related it to anisotropic filtering. Nvidia has a lot to explain.

3DCenter, for the original article, is here in English while the Computerbase German article is here. We will ask Nvidia what is going on but we think there's something up. At lease the guys proved it isnít a hardware bug - it's a driver problem only but performance drops dramatically as soon as you resolve it.

ditto to you. at least he generally has helpful/informative posts. at least 20% of your posts are of the above 'quality' :rolleyes:
