Just wondering, why didn't you run 2-pass shadows in iRacing? That has a significant impact on frame rate. Great review, but you weren't really "maxed out" in iRacing.

As for the thread I've asked or pointed out Vsync and 120hz which for a sim are quite important are they not? Ignore the other thing and concentrate on the points that are actually relevant and certainly no less than discussions of what CPU people are running.

To run Vsync you need a display with VERY LOW (near zero) input lag and a video card that is good at handling Vsync. I haven't seen anyone test Vsync on the 680, but I know running Vsync (at 60hz) was very important to me, so I picked the monitors with the lowest input lag (Dell U2312HM) as well as the card which performs well with Vsync (AMD 7970) and Vsync runs without any noticeable input lag.

I'd like to see this 680 tested with Vsync enabled to see if it adds much input lag. The vast majority of people can't satisfactorily run Vsync, but I've heard that Nvidia is supposed to have some kind of "adaptive Vsync" in the next driver release, so that sounds promising. Now they just need to add support for 5 monitor surround and I'll be back in the Nvidia camp!

Great review and thank you for sharing.

Any chance you could try out rFactor 2 and pCARS on a single screen with a full grid to see what frame rates that you get with the GTX680?

Great review Seahawk, I run 2 GTX 570's in SLI and my next card will be the 680 4GB card. I don't think pCARS is as good as iRacing graphics just yet but perhaps once CARS comes out of Alpha, Beta and they fixe the over blurry graphics. :) Almost everyone that races pCARS has a low frame rate and once SMS optimizes the graphics we should see a vast improvement their.

I'm very tempted by the GTX 680 4GB. I currently use a single GTX 560 ti, and it's fine, but one of these days I'd like to get on the triple screen train, and I'd like to do it with a single GPU solution.
 
Has either of them proposed to the other yet? Such passion, over video games no less.
OT: what is the resolution this card can produce with tripple screen 3D, 1080p or higher?

Seems more like a question of who has the biggest «rig» to me but Im just a 40 year old child (I dont play Iracing) so what do I know?
 
Stop the pointless and off topic insults and bickering now or a few of you will end up banned.

I read somewhere that it is not recommended to run 2-pass at the same time as everything else. I will try turning it on and report back on the results.

I'll test that out in the next day or two and let you know the results. Haven't tried single screen yet.

The GTX 680 4GB would be the card for that, a single card would be awesome as well for us nVidia users. Going triple screen is the easiest way to improve ones racecraft IMO.
 
Yeah, I'm pretty sure I'll go with the 4GB as well after all. I know I initially poo-pooed the idea when you and someone else suggested it to me in my build thread, Left, but thinking about it and seeing the price of the PNY (or was it Palit?) 4GB that's just been released, it makes more sense to just save up that extra £100 or so than to buy a 2GB, sell it at a loss and then have to spend more on the 4GB. Buy cheap, buy twice and all that (not that £440 for the MSI 2GB is cheap, of course!).
 
@neema-t : i think waiting for the 4Gb version is a wise decision (like i advised you)

Just made me think about one of the first "fast' nvidia graphic cards i bought years and years ago: It had a stunning 32MB of memory and it cost me a small fortune :)

It would love to see a review which covers both the 2GB and 4GB version running at 5760x1080 on all the popular race games.
 
Hey guys,

I want to thank everyone who has cast their vote already. With 1 day to go (ends tomorrow - April 26th), I'm down by a few votes. If you haven't had a chance to vote yet, please take a second to do so. . I've copied the info that I posted previously below. Thanks a lot.

I've put my resume out there to try to be selected as a community tester for the upcoming Fanatec Clubsport Wheel. If you are able to cast a vote, that would be great. One more thing...."Read my lips....No new taxes. :)

I just read that the 4gb version will provide somewhere between 4 - 12% increase in performance over the 2gb version. Not sure if they meant frame rates or what. Just comes down if you think 4-12% is worth an extra Ben Franklin (or $100 for guys outside the US). :)

Had a chance to do some quick testing per your request.

rF2 - Single Screen - FXAA and HDR on - AA none - avg 60 fps
rF2 - Single Screen - FXAA and HDR off - AA Level 8 - avg 60 fps

pCARS - Single Screen - Practice (solo) - Day - Watkins Glen - avg 80-85 fps
pCARS - Single Screen - Race (20 cars) - Day - Watkins Glen - avg 75-80 fps
pCARS - Single Screen - Race (20 cars )- Night - Watkins Glen - avg 65-70 fps

Watching the replay of the night race, the fps dropped to around 45 when the camera was viewing a large pack of cars coming toward you with their headlights on. Increased to around 60 fps when viewing the rear of the pack (facing tail lights).

Yeah, I've just been reading around for myself and this does seem to be the case. I think I'll go with an MSI Twin Frozr III 2GB if/when they're in stock here after all, they're already £470 ($762 US) which sounds a lot pricier than in the States anyway. I could do with saving a little...


Edit: Actually, you know what? I change my mind so often I might just shut up and tell you what I chose when I've bought it.

I am pretty sure that 4-12% would not be OC, I'm guessing it will have a significant OC performance compared to the 2GB version.

Hi Seahawks1Fan,

Thank you for sharing the frame rates for a single screen, that's really interesting results. Am I correct that you were running the games at 1920x1080?

I was expecting higher frame rates for a single screen, but as both games are relatively early in the development cycle I'm sure there is plenty of optimisation to come that will improve frame rates before the final release.

Thanks
James
