    I race with a 7850 2Gb, that has been handling rF2 fine with a i5 3570k for a wee while now. Going back a few generations of cards, and they can still produce decent results.

    The thing I forgot to mention is that ISI might have an idea on where rF2 spends all it's processing power at it's disposal. I wouldn't think the graphical side of things isn't what is having a big impact on fps, but more the physics processing behind the scenes. They may have also been able to figure out that it won't give them as significant of a boost going to DX11, being that it won't be affecting those areas of the sim.
    The tyre and physics systems being so complex and processing intensive I wouldn't think will be sorted with DX11.

    I'm not sure it's physics being the issue, rF2 seems to not benefit much from CPU upgrades. But I agree I think the average user is fine with how rF2 runs at this point, I've had less and less complaints about performance from league members this year. Some ultra high resolutions and VR stuff will indeed benefit much from DX11, but to the average user who runs at around 100 FPS, adding another 100 FPS makes little difference. Soon GTX 1000 series cards will become mainstream and then that 100 FPS benefit already comes from updating your GPU. I think a high-end GTX 700 series card is already giving the performance needed to run rF2 at almost every maxed.

    The Matsusaka VRAM thing I'm 99% sure is not going to be improved by any DX update, it's just that the high-poly objects and high-res textures used on this track take up a certain space in RAM, nothing of which any DX version can magically compress to my knowledge. Race tracks are a bit problematic because they need to have everything loaded into VRAM at once, unlike games like GTA V, which dynamically fetches stuff as you move in the world.

    Wellll it's hard to argue with that sample size.

    Well maybe i'm an average user or not but with my setup i can just hold everything at 60fps. So a performance boost without me spending again a lot of money on the hardware side would be very welcome

    I didn't see arguments like #382 in iRacing forums when users was asking DX11 support. What an stupid company iRacing is when didn't think that soon GTX 1000 series cards will become mainstream and there is no benefit with DX11 support:)Seems that iRacing is waisting lof of time and effort to all kind unnecessary support like: "What’s New in Version 368.69 WHQL iRacing: Motorsport Simulator - added DirectX 11 SLI profile" when the the average user is fine with hes single screen 24" 60 fps system :) Posts like #382 makes me also to wonder why the hell I own modern car when I can get from A to B also with T Ford or with 40 years old Lada :confused:

    Too late for what?

    Is the world going to end? Has there been some shocking revelation that sometime soon the game will become extinct?

    Maybe stop over analysing statements and take them for what they say rather than reading between lines that aren't there. Go enjoy the game... I mean, that is what it is there for right?

    iRacing has limitless money for game development while ISI has one guy working on graphics engine, that's the difference. Also I think ISI is working on other game at moment, so even less resources to do some whole game engine rewrite that DX11 requires. I remember in 2013 when first Silverstone version came out, it ran quite poorly and it was justified to criticize rF2 for poor performance back then. After that ISI has only optimized the engine without bringing any new FPS consuming effects, new track versions have improved FPS stability, GPU drivers have improved, and finally average GPU performance according to Moore's law has tripled since then. I think the performance complaints 3 years ago were very justified, but not so much anymore since rF2 hasn't got any heavier to run.

    Your description regarding rFactor2: "GPU drivers have improved, and finally average GPU performance according to Moore's law has tripled since then" is placebo. GeForce 700 Series Release date May 2013 and GeForce 1000 Series Release date May 2016. I have my doubts that 1080 is outperforming 3 x 780 and I have not experienced any improvement or performance boost with Nvidia drivers since release of rF2. New ISI tracks are improved as you state but the problem is that there are loads of 3pa tracks which don`t perform well. rF2 is modding platform and we can not expect that all moders are redoing they work. I think that only DX11 can give boost which is needed to 3pa tracks.

    I just upgraded from the GTX760 to the GTX1080. In texture fill rate alone, it's something like 2.75 times higher. In terms of real-world tests (I did a full computer rebuild): I was getting 30-50 fps in Doom on the old card/system, and now am getting capped at 200 fps (Vulkan).

    ...just food for thought.

    King vs king Titan Z is GeForce 700 Series card :p
    Maybe you and many others should focus and look sometimes in ISI technical forums and find out is going on with rF2, perhaps start with this thread : http://isiforums.net/f/showthread.php/29462-High-frame-rates-but-stuttering

    Would take too much for rF2 to look like this?


    The Silvertone video realy looked like rF2 with some shader work and lens flare to me (but the les part is not important, it sucks lol)

    I stopped by the store on Friday and I bought two GTX 1080. Triple sceens 120fps game play in rF2 is still not possible with descent in game settings with triple screens, single card or SLI.

    SLI GTX 780Ti, whql 353.30, sli bits : 0x02D04005 (LEGO Batman 2,.....) is still undisputed champion of rF2 and is able to deliver locked 120 fps gaming with descent settings.

    ....rF2 seem to be frozen in time. :(

    If I had read yout statement last month, I wouldn't ever bought my new system (i5-6600k + single iChill gtx1070).
    Thanks god you wait until today.
    I now have 5760x1080 everything maxed to the max, fps never goes below 90, but much of the time sits comfortably above 120. Even in Suzuka.
    No stuttering no nothing.
    My problems before were much probably caused by amd cpu+gpu.
    Are you absolutely sure that your system (cpu+memory+mb) is able to feed the gtx1080 sli?

    If you click that four colored icon below my user name you find out how my system is.
    What did I wrote in my post # 393? This: "Triple sceens 120fps game play in rF2 is still not possible with descent in game settings(not all maxed out) with triple screens, single card or SLI." I think I made my point 100% clear, what is your point? Perhaps justify lack of rFactor2 missing SLI support or pure gMotor 2.5 graphics performance? Or is it something else?

    Tim Wheatley wrote recently in comments under this video:

    Yes, he is ISI employee, but would he need to promote their product through lies? Well, what do I know, I can't verify the fact on my 2012 system.

    My system with a GTX 780 and decent (your idea of decent may vary though?) settings can do 100-120 FPS with triple screens and multiview.

    I usually keep track detail to Medium, shadows to medium/high and reflections low.

    For me, having ~100+ FPS is far more important than ultra shadows and reflections.

    I don't feel like rF2 is worse than other sims I have. Quite the opposite actually, if you consider the fully dynamic lighting.

    Take your favourite car to Suzuka from 6pm with 5x-10x time acceleration if you haven't yet.

    Nobody is accusing Tim to be a liar, but have you never seen anybody from ISI to give technical support with GFX settings? It is easy to make end to all complains about rF2 graphics performance, it is just to post those amazing settings to technical forums, right? Or perhaps you can do that?

    My experience shows that triple screen 5760x1080@120 fps everything maxed except shadows, is perfectly possible with a single gtx1070.
    Seems strange to me that your top notch system isn't able to do the same (or much, much better fwiw).
    Enough clear now?

    Since you are running rF2 so well, may I ask what amount of AI cars you are using?

    I have a i7-3930K@4.5GHz wit single GTX980ti and 1080p triples and I definitely can't keep 60FPS locked even with reduced settings (mainly shadows medium, reflections off). That means depending on a car and track used, I can get FPS dips all the way down to around 50FPS with 20+ AI cars out on the track. This happens usually at the start when its crowded and track has most details present with all the grandstands and pits and other parts of the track usually run just fine. This is of course very car and track dependent, some combinations stay 60FPS locked all the time. Genreally, ISI cars and tracks are well optimized and have good performance, while not surprisingly some mods can be FPS hogs. For example Flat6 is notoriously hard on the FPS and when driving it, I usually drop shadows to low and it can keep FPS locked at 60 all the time with around 25 AI cars on every track.

    Sure, with just few AI cars and without v-sync I can pull 100-200 FPS, but I like to race against more than 3-5 cars. In the end it is useless to compare our performance if we don't know our system specs or our ingame race/event settings including track and car models used.

    All in all, rF2 graphics engine is really heavily CPU bound. On most cases when I get below 60 FPS, my GPU usage stays below 100%. PCIE 2.0 vs 3.0 performance difference tells something about CPU overhead too. That is also the reason, why graphics card upgrades don't necessarily lead to significantly improved performance.
