Hey guys, first off @ Sector3 Team: Awesome (!) job on RRRE during the last couple of months. Bought almost all of the store content immediatly after it went in to open beta because of the huge potential I saw, but began to worry after some time about the direction the game was taking - missing AI races, no multiplayer, features going into DTMEx2013, but not into RRRE and so on. But for the last couple of month this game has shaped into the racing game of my dreams, nice content with DTM and GT Masters, awesome handling, even more awesome sound, championship mode, multiplayer for everyone. Looking forward to the 2015 content, hope there's some big marketing campaigns coming because at least to me, RRRE is clearly superior to any other racing sim currently out there or coming in 2015, but seems to be less known among the general gaming audience than some of your competitors. Thanks and keep up the good work! Sorry for the long intro, on topic now: Are you currently planning to add SLI support? I am running RRRE on one of LG's 21:9 3440x1440 pixel monitors, powered by twin GTX 970s. The game looks and feels absolutely stunning, but as only one GPU is utilized, I do run into some performance issues from time to time, espacially when increasing MSAA or number of cars on track.
Good question! I would love to see some SLI support.For the moment, I am using a modified RaceRoom SLI profile. It performs, but you can see its far from optimal. For me the SLI support is a must when driving on triple screens. That brings me to my second question. Is there anything planned in the near future for triple screen users? I love the way Kunos has implemented triple screen support in Assetto Corsa. But since I am becoming a R3E addict, it just made me wonder.
I have modified and tested some sli-profiles, but for me rrre runs best on a single card. An official sli support would be nice, yep...
Its a pity because even on one single card this game is heavier then any other sim out there.... it used to kind of work with windows assessment tool in SLI but it doesnt anymore
0x00400405 this SLI bits bump the performance hugely but the menus flicker like mad i dont get why Sector3 doesnt experiment with these things :/ Actually those Sli bits DOUBLE the FPS ....
Hope someone from Sector3 takes a loot at this video... kinda annoying loosing all this graphics power... specially since this graphics engine is really far from being OK in a single card..
Hey @Lino Carreira , Interesting video. My experience has been fairly similar I suppose. SLI isnt at all supported by R3E at this time which is a bit of a bummer. I havent done anything as in depth as you as going into Nvidia Inspector to force SLI, but from goofing around with the game I have noticed that if I turn my 2nd gpu off, disabling SLI, I get better performance than if I have my 2nd gpu active. Since this game doesnt support SLI, its kinda buggy when having a 2nd gpu active. Im sure forcing SLI gives equally odd results like your vid demonstrated. Try disabling your 2nd gpu from the Nvidia control panel and see what kind of fps you get. It very well might be better with the exact same settings you run. On that note, it would help if you supplied what your settings are. Are your in-game settings maxed out? From the video, it looks like you are using an ultra wide display. Is the resolution 3440x1440? It seems like that to me at least. Using a single gpu in this game, even if it's a gtx 970, pushing that resolution with maxed out settings is quite demanding and system intensive as Im sure you know. If you havent, maybe turn down AA and see if that gives you a boost in fps. For me though, this game is quite well optimized and isnt any more demanding than any other sim I play. Sure original rFactor and GSCE may give better frame rates, but I think R3E is a bit more demanding with its better visuals. So the balance is still there. For the time being, you might just have to be content with using 1 of your gpu's power in R3E unless you can brute force SLI to work somehow without being buggy or giving that awful flashing before entering a track like your video shows. R3E isnt the only sim out there that doesnt support SLI in any way, but at least for me, I hope we will see support for it one day.
Sorry forgot to mention, yes, it is 3440x1440, AA just on 2x and FXAA, also shadows on medium, and i always deactivate motion blur... , reflections on low also Will try to disable the second GPU , as far as i can see it already behaves as if it was turned off with sli bits for DX9 at 0, but ill give it a shot Nevertheless my only complain at the moment is becoming blind with those flickering menus, this wasnt happening before, and as you can see with the 2nd GPU in game it doubles the FPS, so i think they are missing an oportunity here just to have those menus that have given nothing but issues....
Ahh, you seem to know a lot more than I do on how to get sli working in games... Even ones that dont officially support it. This is honestly beyond my level of knowledge here, so if you have some understanding on how to get sli to function well, that would be welcome info for me. In my attempts to get it to work in the past, which werent as in depth as going into Nvidia Inspector and setting it up in there... I just had more success getting the game to run well by disabling my 2nd gpu for R3E. Not that this is any sort of "fix" since you wont be using your 2nd gpu at all this way... but, alas, Im not sure of any other way to make things function better. I guess I should mention that I only run a single screen at 1920x1080, so it isnt that demanding. I have most settings turned up all the way beside shadows and reflections, and only use 2xAA. This gives me rather good fps on my gtx 660 (~60-80 in races, ~80-100 solo practice). So for me, sli would be nice if it worked, but I dont really have that many more settings to turn up It was interesting though, after you made a change in your video, that the fps was just about double what it was before... but those flickering menus made me dizzy to watch lol. Sorry I cant be of any help, but, just know you arent alone and sli doesnt quite work yet for everyone. Cheers
Yeah, i cant be bothered to play with the menus flicking like that, ill just leave on one card with lower settings, anyway ill keep trying stuff but would be cool someone from Sector3 ( after they fix all the more urgent issues ) would take a look at this ... In case anyone with SLI wants to give a shot ive been fidling with other Sims too and so far this are the bits im using ASSETO CORSA - 0x000110FB IRACING - 0x02400005 (DX9) RFACTOR 2 - 0x02C00405 (DX9) RACEROOM - LFS - PCARS - 0x000110FB GSCE - 0x02400001 (DX9)
You can get crossfire to run both cards using AFR and frame pacing but it's far from ideal, flickering like crazy and text characters in the overlays are jarbled. I tried it for a few sessions and went back to single card. I did see significant FPS increase though, especially noticeable in the usual laggy spots like Sonoma turn 1.
After some testing, same results. Very good performance increase, but flickering shadows and menu. If one day we find a profile that works, SLI for R3E will be worth while.
Hello, I just installed SLI of 2 x Asus GTX 970 Strix OC 4GB , I am very disappointed, no improvement in FPS, it works even better with a single card. A driver in our team installed a Crossfire of 2 x R9 290x and her good results with this configuration. Sector3 quickly, tell us if you plan to improve it
Always better off with one beefy GPU over SLI, ran multiple GPU's for years, double the expense for a mediocre performance increase, will only ever use memory of one card and seeing vram is the most important factor I see no point (IMHO). Flog your 970's and get yourself a 980ti!
I now have a "Dual GPU" card (was given too me broken, so fixed it), game still runs great on a single screen but, I'm now with you guys and would like to see CF/SLI support as I'm currently only using half the cards potential.
