NVidia GTX 670, First Impression

Quite often AMD cards have a higher peak framerate than Nvidia cards. I believe it's that wide swing in variation from max to min framerate which is probably responsible for the microstutter. It can be quite substantial. That high to low and back to high again is really not ideal. I just wish we could somehow figure out which factors are most responsible for it.
 
Guys, maybe a bit off topic, but I couldn't think of a better place to ask......

My nephew has got a GTX 480 1,5Gb and he is offered a 670 (don't know which kind) and he (and I for that matter) would like to know if that is an improvement.
Now......I do the searching for him (don't ask ;) ) and I do find a lot of charts, but never these two in the same one. It's impossible to make a decent comparison because "the other chart" is always made with different hardware.

Do any of you guys know how these two relate?

Again; sorry for intruding the topic but I didn't want to make a new threat just for this.
 
The extra .5GB of video buffers won't hurt at all on the GTX670. It also has a more efficient core. What is the basis of the offer...card plus money for the swap?
 
As you say you don't often see a 480 v 670 and yes it should be an improvement. One site I did find a comparison was here testing over a variety of games/benchmarks (no rF2 unfortunately), note at the time of this test AMDs 'Never Settle' drivers had not been released.

According to AMD's David Baumann (as reported in TR's article), AMD is now rewriting the entire driver again since they found out that the memory management in GCN architecture is entirely different to prior GPUs.

AMD plans to release few driver updates in the early part of this year. Can't wait to see the test :)

This might help: http://www.hwcompare.com/12527/geforce-gtx-470-vs-geforce-gtx-670/ as it gives you theoretical performance of each card based on their basic/reference specification.

I use that site a lot when I was in the market looking for a GeForce card to replace my Radeon HD5770. And in the end I chose GTX670, since it gives me 270% improvement over HD5770 in theoretical performance, and also good 'extras' such as PhysX, and the price is more affordable than GTX680 or GTX690.

EDIT:
Oops, sorry I gave you the wrong comparison! Here's the correct one:

Thanks for the response guys; I know enough to tell him.
The guy selling it, wants 275 euro's for it and in my opinion; that's a lot of money for a 30% upgrade; I just tell him that.
 
I just got a 670 today to replace a 6850, went from 1600x900 to 1080p, AA from level 2 FXAA to Level 4 AA, and turned up the rest of the settings to full. The thing is I still get flickering lines and barriers in the distance, can anybody tell me where I'm going wrong?

You aren't doing anything wrong - it's a common problem with ISI games (from my experience). The only way I managed to get rid of these flickering fences and barriers (and jagged white lines) was to use Nvidia Inspector to apply some Sparse Grid Supersampling.

I use level 3 or 4 AA in game and 4x Sparse Grid Supersampling from Nvidia inspector. You just need to change these two settings from within Inspector - 'AA Transparency Mulitsampling' (change from disabled to enabled) and 'AA Transparency SuperSampling' (set this to 2x or 4x SparseGrid). Obviously the more SparseGrid you use the lower the framerate will be, but your 670 should be able to apply at least 2x which will be an improvement.

Good luck!

Edit - maybe try this without FXAA applied as well. You can still use it with SparseGrid, but I think it's better without FXAA.

However the latest rF2 build combined with the latest AMD driver (12.11 beta 8) bring back the micro stutters, even worst than before.

That;s is simply not true for all systems, my HD6950 Crossfire is as smooth as silk, all details at MAX, 1920x1200x32 res
16xAF AAx3 and its locked at 60fps with V-sync, it never drops below and is real smooth?

with 12.11 beta 8 btw

I simply wouldn't want to swap to anything else just now, as its running sweet

with v-sync off btw it will get as high as 178fps, but picture is smoother with v-sync on, no tearing

Thanks for the advice, I tried 2x and 4x super sampling on transparency from within Nvidia control panel, it does seem to improve it slightly, 4x starts to drop framerate a bit so I'll have to stick with 2x for now. Fingers crossed that this is an area where ISI are able to make improvements in future.

Okay, but I should point out that SparseGrid is not the same as the normal SuperSampling you are using from control panel - SparseGrid is better at fixing the problem you have, and in some cases it doesn't cost any more fps than actual SuperSampling (depending on the card). I recommend you try 2x SparseGrid instead.

Nvidia Inspector is a very tiny program and easy to use - it just extracts to a folder and runs from there (it doesn't 'install' itself anywhere). It works in conjunction with the normal Nvidia Control Panel - you can use either as they both do the same thing (so if you set 2xAA in Inspector's global profile you'll notice 2xAA is set in Nvidia Control Panel's global profile too), the only difference is Inspector has more advanced options. It's not like installing some big piece of software - it's very small and you can just delete the folder if you don't want it anymore.

Sorry for going on, it's just I know SparseGrid fixes this problem a lot better than normal SuperSampling.

I'll be quiet now. :p
 
Thanks for the tips ForthRight! I have used level 3 AA and FXAA till now. FXAA for extra AA cause aliasing in stereoscopic 3D is very annoying. Will try SparseGrid without FXAA.
 
You should use 60 FPS as cutoff (aproximately humans' vision "refresh rate"). 30 FPS is too jumpy when you get used with 60 FPS. More than 60 FPS is not really noticeable...

Because I want to run rF2 at more than 30 FPS :) This was my setting with HD5770 by the way.

Now I can run with Full circuit detail and still get more than 30 FPS all the time.

When I'm recording this video with GTX670 installed, I had to kept all previous settings in order to get equal view.

I am new to nvidia so didn't know about nvidia inspector before but it is a nice little program. I have tried sparse grid super sampling on tranparency briefly and it didnt seem all that different to normal super sampling (which was a great improvement over nothing anyway), I will have to test more when I have more time. Flickering on the white lines in the distance is still not great, maybe it is an area in which not much can be done.
 
Super Sampling (SSAA) is more expensive, in terms of performance. Multi Sampling AA plus Sparse Grid AA gives me an acceptable anti-aliasing, better than FXAA I think, but with better performance than SSAA.
 
Indeed SSAA gives around 100fps where as MSAA will give me around 178fps,
However I prefer the look of SSAA and keep vsync on so only need 60fps anyway lol
 
True. SSAA quality is still the best. Hopefully ISI will implement TXAA as well, since the quality is supposed to be better than FXAA, but the performance is almost equal to FXAA.

Well, this is my second impression of GTX670 after spending about 6 hours testing it.

Now I can run rF2 smoothly with these settings:
- 1920 x 1080, 60Hz, 32-bit
- HDR on, FXAA off, Anti Aliasing Level 1 (AA is quite good at this level, but the shimmering effect in distance still there)
- Environment Reflection on
- Road Reflection on
- Sun Occlusion on
- 25 AI, 20 visible cars

Wet race is playable now. Previously, with HD5770 my system would hit below 25 FPS in the wet. In terms of image quality, both cards perform really well.

Hi! Im the guy form 660ti 3 screen try out! :P

I see you bought a 670, could you tell me whats the size of you screen/monitor?

I guess Im gonna try a single 40" monitor
