    Hello triple racers!

    I would like to know:
    What kind of hardware do you use?
    Are you able to race with steady frames on a full server on any track with multiple cars to choose?
    (shortly describe your experience, grafic settings, when/how does it struggle)

    I hope we will find out what kind of hardware is enough to get a decent triple screen experience
    and what kind of hardware is capable of handling everything maxed out 32 drivers on nords each in a different car.

    Thank you for your contribution.

    What I have learned from the first 20 posts:

    A.I. needs more cores than multiplayer
    over 16GB ram doesn´t do much
    nobody uses AMD cards

    Barely capable systems:
    4cores 4GB HD7970 3x24"
    4cores 8GB GTX770 3x21"
    6 cores 12GB GTX760 3x 24"

    Decent gameplay with some compromises:
    6cores 8GB gtx970 3x20"
    4 cores 16GB GTX770 3x20"

    Pretty much anything anytime:
    4/8 cores/threads 16GB GTX1070 3x21"
    6cores 32GB GTX1080 3x24"
    4/8 cores/threads 16GB GTX1080 3x28"

    For decent gameplay you need
    6cores(AMD) or 8 threads(Intel) 16GB Ram GTX970/1070

    Official RECOMMENDED SYSTEM REQUIREMENTS: <---for single screen , i assume (found on assettocorsa.net)
    Processor: AMD Six-Core CPU, Intel Quad-Core CPU
    Memory: 6 GB RAM <---is this a typo?
    Graphics: DirectX 11 (AMD Radeon 290x, Nvidia GeForce GTX 970)

    I bought my PC several years ago to handle "Live for speed" on three displays.
    Then AC-Tech preview came out, followed by AC with a handful of cars, followed by huge tracks, a lot of cars, bigger online grids, post processing and things got worse.
    With AC still beeing in development i hoped for some optimisation and restricted myself to less populated servers with only one car model. Now i am sitting here with the processor that is listed on Assettocorsa.net under "minimum requirements" and a Radeon HD 7970 (5760x1080) next to 4GB of ram.
    AC is ugly to look at (everything turned down) and still annoys me with it´s slideshow effects if there are more than 3-4 guys online ;)

    I think I am getting the "decent" triple experience. Absolutely not everything maxed out, far from it, but looking good enough. Basic Post processing, 2x AF 4x AA, high details, shadows turned down.

    Current system: See signature
    It can run everything (full grids, multiplayer, etc) with the game on max settings (except PP=OFF, reflections=static) and it never drops below 60fps with vsync=on. With vsync=off, FPS hover around 110fps hotlapping and ~80fps on full grids during race starts.
    If I enable PP effects, then my FPS are above 60fps when driving solo, or perhaps 3 car grids max. Larger grids can result in FPS drops to the low 40's. I disable PP because of the performance drop and also because I like the clean look of the game without them.

    Earlier system: same as signature but an i3-4160 (instead of the i5-4590).
    Same settings as above but the game would drop to ~30 fps on full grids. You really need a quad core for this game, unless you only plan to hotlap, where I would still get steady 60fps with the i3.

    The game only appears to need slightly more than 8GB ram when loading big tracks (Nords) with very large grids using different cars (repeats of same car does not add much ram). At least this is how it is reported by MSI afterburner under page-file usage, which I understand is the system memory usage. This is not a big deal as virtual memory on the SSD appears to handle the extra RAM requirement well.

    I wished I could tell something sensible, but no triples here.
    But a call to help: This guy is the one who picked me up in my very first AC MP session, and taught me everything I know about simracing. He also invented Helicorsa, helped a lot with MR, and I'd be so glad to see him racing again on a server with more than 3 drivers online

    My 760gtx does about 50 fps with other drivers around, full grid gets stuttery though. I don't drop settings to the point everything's ugly though. PP is not really optional to my mind, same for decent AF.

    As far as I know, the number of AI or other cars if on-line that your system can cope with is more down to CPU than GPU. Please feel free to correct me if this is not so. This may mean a jump in CPU power which may need to be accompanied by a replacement Mother Board. Once the CPU can cope with the number of cars then it's just a case of coupling that with a GPU that will give all the eye candy ;)

    The system that @PhilS13 is running seems good and is similar to where I started out. My current pc specs are listed in my sig but are way over the top of what's needed for a more than satisfactory experience :D

    I'd also recommend using the ED tracker with triple screens unless you end up going down the VR route. I had mine set up on triples so that I looked at the middle screen and used the Left and Right screens to show me what was going on to either side - you can set up a curve or profile to dictate the amount of movement on the screens versus movement of your head (and eyes). There is an old thread about it here http://www.assettocorsa.net/forum/index.php?threads/edtracker-and-assetto-corsa.31254/ and the site for the device is here http://www.edtracker.org.uk/index.php It's a good, cheaper alternative to other tracking solutions and there may be a wireless edition now. It works using the earths magnetic field so as long as there's no major sunspot activity it works fine :p.

    Since I upgraded my system to head down the VR route I've got a GTX980 and an EDtracker going spare. Feel free to start a conversation, I'd be happy to help out the father of MR to get up to speed with AC.

    iam using a potato for triple screens, works decent :D
    gtx 770 2gb
    8gb ram

    no aa
    medium graphic settings
    pp filter off

    i get a around 50 to 100 fps depends on how many cars on the track and depends on the track.

    the worst thing about triple screens for me is that nvidia surround is ****, and it takes too many steps for it.

    Just one thing I've noticed on my old i7-920 before changing to a Ryzen 6 core:

    Driving online is actually a lot less demanding to the CPU than driving with the same grid offline against AI.
    Online AC pretty much only has to handle the physics of your own car, the cars are just placed by the info you get from the server.
    Against AI the cpu also has to handle the other cars physics and the AI themselves.
    In short, I could easily run a 24 grid online race but (depending on car(s) and track) I could run 16-22 car AI races with no to fairly low stuttering.

    Unless you want to go into high fps you will be fine with a Ryzen 5 1600X or 7 1700X or for Intel a Hyperthreading 4 core with high clock or one of the new 6 core models.

    The bigger issue will probably be the GPU to handle the triple screens.

    A 1060 6GB or RX580 8GB wil probably be capable, but a 1070 / 1070 Ti / 1080 might be the better investment considering future titles.

    In what way ?

    I don't have any probs using NVidia surround, I just set up the screens as one screen at 5760X1080 with a few extra pixels to cover the bezels. Works OK for me if I'm not in the Rift. I haven't even bothered using the triple screen set up in AC.

    @Schnipp Cheers for clearing up the differences between AI and On-Line wrt CPU requirements, I wasn't sure.

    Hmm a couple more things I have an opinion on.

    "nvidia surround is bad" yeah, I don't use that, I play windowed mode at all times. All the important options for getting a realistic view are in the AC triple screen app. Find out what they measure, enter it according to your real setup, done.
    "use headtracking, lock to horizon, etc." personally I have to play with it locked 100% to the car (turn off lock to horizon, set all movement sliders 0%, no real head movement), anything else gets me motion sick. so ymmv.

    I have been running triples for a while, mainly using SLI configurations, there seems to be problems
    with SLI more than running triples depending on nvidia drivers but right now my setup works fine.

    CPU i7-7700k, 16GB RAM, OC 9-14% (on result below).
    7680x1440 GSYNC
    AA:4X AF:16X SHDW:4096 BLUR:0
    PP: QLT:5 HDR:1 FXAA:1 GLR:5 DOF:5 RAYS:1 HEAT:1

    Using motherboard with 2x8 PCI slots

    1070 SLI (had lower gfx settings than above)
    POINTS: 12684
    FPS: AVG=86 MIN=58 MAX=177 VARIANCE=0 CPU=37%

    1080TI SLI
    POINTS: 17385
    FPS: AVG=118 MIN=26 MAX=217 VARIANCE=7 CPU=51%

    Using motherboard with 2x16 PCI slot (had to upgrade due to the need for 80mm SLI spacing)

    DRIVER 388.31 (stutters, can not use)
    POINTS: 21377
    FPS: AVG=145 MIN=14 MAX=258 VARIANCE=33 CPU=69%

    DRIVER 385.42 (stutters sometimes, runs ok)
    POINTS: 22633
    FPS: AVG=154 MIN=24 MAX=269 VARIANCE=34 CPU=69%

    DRIVER 384.94 (stutters sometimes, runs ok)
    POINTS: 22175
    FPS: AVG=151 MIN=18 MAX=267 VARIANCE=41 CPU=66%

    DRIVER 388.43 (seems to runs ok)
    POINTS: 22849
    FPS: AVG=156 MIN=12 MAX=271 VARIANCE=39 CPU=68%

    Lately I have limit the fps in-game to 90fps, that seems to help against the stutter
    (it help so I have not tried so much going back to 120fps, max hz with triples)

    Also interesting to see that 2x16 PCI affected performance, with rF2 there is known that
    PCI buss is affecting performance but on general benchmarks it shows no to little impact.

    Does this affect performance? Might start doing this, Nvidia Surround is terrible. It's like people at Nvidia think "Triple screen, LOL who has that" for past 10 years

    Requires closing random programs before it's possible to switch modes (because "Close all" button would be too easy), doesn't memorize the order of screens, random numbers assigned to the screens. Can I even change somehow what screen is seen by Windows and 1, 2 and 3 respectively? Without connecting them into GPU in different order. The keyboard shortcuts don't work reliably or at all... because being able to press 1 button to switch surround on/off would be.. too easy. And the list goes on

    Yes, the switching between modes works very nice.......

    So, is running triples using windowed mode on an non surround setup possible?

    It won't automatically put the triple resolution in the dropdown options so you have to edit AC's config directly, or never even touch that setting after you turn off surround. Other than that yes it works fine with surround not set up.

    I can't say if it affects performance because Surround refuses to give me native resolution. It's probably a bit worse since win10 has no way to turn off gpu acceleration on the desktop except going fullscreen.

    Nvidia surround enabled btw.. Windows 7 64-bit.

    Triple Screen
    fullscreen rendering: yes
    vertical sync: yes
    63fps framerate limit
    4x anisotropic filtering
    2x anti aliasing samples
    medium world detail
    medium shadow resolution

    low smoke generation
    show smoke in mirrors: yes
    enable post processing effects: yes
    default effect preset
    all effects on normal
    crepuscular rays: yes
    heat shimmering effects: yes
    fast approximate anti-aliasing: yes

    normal mirror resolution
    high quality mirror reflection: yes
    low reflection quality
    static reflection rendering frequency

    Very decent FPS on 12-18 car grids consisting of 4-5 different cars when racing in my community. Nordschleife server usually doesn't give any problems neither. Some mod tracks give a bit of stutter at times, but I guess that's down to poor optimization. Some specific parts on Kunos tracks give trouble (Vallelunga chicane near finish with 6+ cars).

    Thank you very much for your participation!
    I updated the first post with a list, some initial thoughts and a first recommendation based on what we have so far. (If you´re on triples, please post!)
    Some guys cant handle/don´t like VR for multiple reasons and don´t want to go back to one screen after trying VR, those might benefit from this thread aswell.
    Those that wonder why they don´t get the performance on triples, can see what component needs to be upgraded.
