    That is the truth, same in game settings and rFactor 2 video settings. Tested with my two rigs.

    MBO: X99
    CPU: i7-5960X
    Ram: DDR4@3000
    GTX 1080Ti
    Resolution: 5760x1080@ 120hz

    My old rig:
    MBO: Z87
    CPU: i7-4770k
    Ram: DDR3@2666
    GTX 780Ti
    Resolution: 5760x1080@ 120hz

    Sorry for you lost mate :(

    I'm sorry too, hopefully someone from S397 takes notice.

    Asus Maximus Formula
    Q9550 @ 3.4
    GTX 960 4GB
    6 GB DDR2
    1980*1020 @ 72Hz

    Matsusaka uses a lot of GPU VRAM and is not built by ISI/S397, and it hasn't been optimized for DX11 either. I would advise to only tests tracks/cars that appear in Studio 397 DX11 workshop, those have been updated for DX11.

    I have 4GB GPU VRAM, plenty for a single car around that track. I tested ISI tracks as well, same result, I will post numbers after LM qualifying is over.

    More news at 11.

    Post-processing set to "none"
    ISI SuperGT Nissan
    Nola
    DX11: 61 FPS
    DX9: 133 FPS

    Mills
    DX11: 57
    DX9: 116

    Laughable, and pathetic.

    It tells me that your post is not helpful in any way.

    It should tell you to look within and not blame the build and rant away obviously aimed at devs

    It can't tell me that because there's nothing to look for within. It's not a rant either. Performance drop is in fact laughable and pathetic.

    Are you overclocking anything? (cpu? video? memory?) If so, at least try with everything set back to default settings.

    re-install rf2 fresh , then run on min settings at first ,
    I'd still run dx11 even if your current hardware is much better on running dx9

    just looked at your spec, you should be fine on low settings, do put an overclock on your cpu if you have good cooling , i overclock my cpu the difference in performance is night & day

    In my effort for trying help you out with your FPS loss, I had to dig deep into historical archives to find information about your hardware.

    CPU: Core 2 Quad Q9550@ 2.83 GHz, L2 cache 2x6 mb, fsb 1333 MT/s, released in March 2008
    MBO:
    PCIe 2.0 x16
    Dual-channel DDR2 1200*/1066 MHz

    I am sorry to have to say this but, It is obvious to all who has knowledge about hardware that your CPU, ram speed and PCIe 2.0 x16 support is bottleneck to your GTX 960. I would never use anything better then GTX 480-580 with hardware like this and would never dream about to use PP in rFactor 2.

    You may find rFactor 2 DX11 Beta laughable and pathetic but in my mind 57 fps is impressive with your specifications.

    ;)

    Just the CPU, overclocking GPU and memory is, from my experience, usually a waste of one's time as gains are not significant enough.

    Thank you, I'll do that.

    Difference between PCIe 2.0 x16 and 3.0 x16 in games is negligible (on single card systems at least). I'm not looking for a lecture on hardware.

    I don't find rF2 DX11 beta laughable and pathetic, I find performance drop (30-70 FPS just by changing one variable) laughable and pathetic, huge difference. And please don't put words in my mouth.

    Forget difference between PCIe 2.0 x16 and 3.0 x16 in other games you are in rFactor 2 now o_O

    TechAde has pointed the finger at the PCI-e bus as to the reason a performance disparity exists benchmarking rFactor 2 on identical GPUs.
    GPU: EVGA GTX 980 SC OC #1 (1550MHz, Mem 1900MHz, TDP < 88%)

    PCIe 2.0 @ x16
    Time: 67875ms - Avg: 145.655 - Min: 113 - Max: 176
    PCIe 3.0 @ x16
    Time: 67627ms - Avg: 187.975 - Min: 153 - Max: 216

    29% average increase, 22% max, and the most important ... 35% min increase on a single card.:rolleyes:

    rF2 is indeed heavy on PCIe, but his midrange GPU should not bottleneck the PCIe 2.0 bus as much. I think it's a combination of CPU, game settings and software (drivers etc.), because I experience 10-15% less FPS in DX11 using the same settings with an old i5-750 & GTX 660 Ti rig. So something is not right for him.

    That's a good info, thanks, rF2 then might be an exception to the rule. I'm not sure how it relates to my problem of losing so much performance just by switching from DX9 to DX11.

    Just to info. I have tested how much ram has to say in rF2 with 1080Ti and hardware from 2013.
    MBO: Z87, CPU: i7-4770k, GTX 1080Ti
    Resolution: 5760x1080@ 120hz.

    rFactor 2 > DDR3@2666 vs DDR3@1333 .> DDR3@2666 has average increase 13% .
