    I want to give insight, where the AI is jumping half a car forward-backward randomly. (like when there's lag in multiplayer)
    It can happen with and without the agressive threading.

    Both of the performance logs are from the start of the race. [And maybe there's a little stuttering in the second log as well, but maybe not too serious]

    DX11 Howston G4 10 AI

    Can you try turning Aggressive Threading on in the config?

    @Mulero we just released another cpu-focused update, give it a shot whenever you can

    @4thworld Clouds are having a big impact on DX11 so I've repeated the tests with sunny weather. No improvement in the latest build.

    AA: Level 8 in DX9, Level 5 in DX11 (no PP)

    Performance it's improved again, Thanks, anyway i still getting more fps in external view than in cockpit, this is strange right? In Nola i can Get 90+ Fps from trackside cam, and no more then 60 down to 54 in cockpit view,if i disable mirror it goes up to 70 (USF2000)

    we saw from your reports that there is a slow down rendering clouds, we're working on it.
    Maybe that's the reason why you're slower in cockpit view.
    Thanks for the feedback again, but let's try to keep the thread structured with the benchmark.
    You can edit your post and notify us.

    thanks again!

    In Assetto Corsa (DX11) external view has more FPS than cockpit, guess it's normal because there are more details on screen in cockpit...

    In this specific thread the most important thing is to keep in mind the comparison between DX9 and DX11, if your DX11 FPS are < than the DX9 post here, we'll keep update until we reach a point where performance in DX11 are at the same level or better than DX9.
    If your FPS is >= than dx11, then this is not the right place to post.

    Again : let's keep this structured as instructed in the first post!
    thanks again.

    Here is my DX11 performance for the latest build. I already sent my DX9 performance. I used the same settings.

    Yes, I did it. Tbh, I couldn't tell a difference, Still a big gap between me turning the wheel and the game noticing it. On top of that the FPS got a little bit worse and even with over 130 FPS I had stuttering. Experience is not really smooth at the moment. If you want me to do a second full Benchmark run with Agrressive Threading enabled, just let me know ;)

    Today's runs:
    I74770 24ram Sapphire RX480 8ram

    My previous DX 9 on NOLA with USF2000 was around 140+ FPS. Today with DX 11 I get upwards of 70 with it sunny/clear (see perflog...clear). When I make it overcast, I lose half that FPS (see perflog...overcast). AA set to 5 post is None. I'm the only car on the track. Eyefinity triples 5900x1080.

    I forgot to mention that the recorder seems to turn off on its own after a short time for me so I can't even get a lap's worth of data.

    Hello, after the updates of 5 May in the DX11 I thought that I was going to get more FPS but my game is still unplayable and has ridiculous FPS compared with DX9.

    GPU: R9 280 3 GB VRAM
    CPU: A6-3650 overclocked to 3,9 ghz
    RAM: 12 GB
    OS: Windows 10 Pro x64
    Controls: Logitech G27

    Track: Indianapolis - Oval
    Car: Dallara DW12

    Here I post my LOG recorded with the CTRL + F and Shift + Space:

    https://www.dropbox.com/s/s3bjqbfw5fntx6o/PerfLog_2017-5-6-1-59-12-.txt?dl=0

    In DX9 I had 60 fps with V-Sync activated in full graphics with the same track and car, but after switching to DX11 I am getting 16 fps minimum and 20 maximum with the same settings, full graphics + None in the Post Processing Effects and disabled Agressive Threading. The game is totally unplayable. I am getting the same fps from the first DX11 build.

    I MUST SAY that I could notice that switching to external camera (Delete key) gave me +30 fps, something maybe will help you to fix it. I say this because maybe you can see in this log that I had those 30 fps improvement and I wanted to say why it happened.

    Here I post my settings in game:

    http://i.imgur.com/8v1GDI7.jpg
    http://i.imgur.com/Mt3rC7I.jpg

    As you can see, the game says I have -1043 MB of VRAM (WTF?) and 11 GB of RAM instead of the 12 GB I have and DX9 dettects it.

    Finally, I must say this is not a CPU related issue, because I know is not the best but as I already said I was having 100 fps full graphics with DX9 and 60 fps with v-sync on, and I also can play Assetto Corsa 24 cars ultra 60 fps and Project CARS high 50-60 fps.

    Track NOLA C. Car : GTR500 2013.
    MAX setting, but in DX11 AA is L4 ( not L5 ), to match DX9, so it will be apple to apple DX9 vs DX11.
    No Post Processing in DX11 as instructed.

    Test are : Single 2560x1440 and multiview angled 7680x1440
    For single 2560x1440, a single GPU and SLI 2 way GTX980 test.

    NOTE : Since RF2 DX11 is new, Nvidia driver 378.92 I use is the default DX11 SLI bits 0X000000 , which is weird, because it does not allow SLI ( 2nd GPU load max 3% only and Nvidia SLI Indicator not running ) if resolution is 2560x1440 or 4K, ........ but SLI will work in 7680x1440.:rolleyes:
    So I ended up using DX11 SLI bits 0X80000F5 as reccomended by other members, for single 2560x1440 monitor in 2 way SLI.

    I did have problem with DX11 Performance Log txt file. Sometime it cuts off at 40 seconds, sometime it does not create the text file. Sometime it works the whole 2 minutes of the test:).
    Sometime it produce a tone when LEFT-SHIFT+SPACE pressed, most of the time no tone.

    I attached Afterburner/RivaTuner log files and also RF2 DX11 Performance Log, not FRAPS because in each I have prepared a graphic view of 1 complete pit to 1 round of the track. Where in SLI troubleshooting a graphic view is a better* tool ( * I discovered a 2 seconds freeze occuring ) and the very same test can be replicated by me to compare to future update of the DX11. The Afterburner logging is 2 data points per second.

    I also have compiled GPU-s Load & FPS DX9 & DX11 in 1 excel file for all the test, to save your viewing time.

    Thanks for this effort. Really appreciate it.

    Did you try clear sky instead of overcast? Many people report poor frames with clouds. And I get double frames with clear sky.
