    last night i make some measurements about gpu vram usage, so the findings are below;

    @1080p aa level 3, full track, player and texture and high opponent settings (gt3 pack cars), pp high, every other settings are full or max
    on nords(nurburgring etc doesnot matter), only with 1 ai car, vram usage is 5500mb, system ram usage is about 6ish gbs and pagefile is about 12000ish mbs, vram usage is drastically higher somehow i donot know why after the update?

    @1080p aa level 2, full track, player and texture and high opponent settings(gt3 pack cars) pp high, every other settings are full or max
    on nords(nurburgring etc doesnot matter), only with 1 ai car, vram usage is 5250mb

    i can race upto 11 ai not a single frame drop on both cases, vram usage not exceeds 6gb, is about 5950mbs ( i have 1060 6gb), sytem ram usage is not higher than 7gbs and pagefile usage is not higher than 13000ish mbs

    but when i increase the ai number, for eq i race with 24 ais mostly, vram usage is 6gb (full), my memory usage is above 9-10gbs, page file usage is about 17000-18000mbs, so the game usage system ram/pagefile when gpu vram is full, and game has some fps drops under 75hz for me but it is rare(mostly on first or the second lap) %99 percent rock solid 75fps but these sttuters makes driving unconfortable, after 3-4 laps on nurburgring gp, system ram usage drops to 6-7gbs.

    i upgrade my pc Ram to 16 giga to help my computer with low 1% fps
    i belive Rfactor 2 needs 16 giga Ram and 8 giga Vram to play Nords laser scan official track or else the graphical backround on track is lagging.

    But the first release of Nords was NOT so Vram intensive. Something changed with the update last week.

    You can run Nords with 8gb RAM

    i have a feeling that 16 giga helps a lot with 1% Low fps and 0.1Low fps
    ofcourse its playable with 8 giga but if you notice graphic lag and your system is good enough memory might fix this weird lag
    Video Ram comes first but a lot of benchmarks shows that 16 Giga system memory improves frame rate stability
    i mean no big frame rate drop that happens suddenly but our eyes rarely notice.
    just test it

    I'm running locked 60fps fine. Depends on what your target is

    Two weeks ago, I was averaging 105-120 fps with 30 GT3 cars. (rx480 x8 i7 6700 16gigs sys ram). Since the new layouts of Nords were released, I am getting 68-70fps with even just 5 ai. And this is occurring at all tracks. The fps counter could be the same at every venue I visit, no matter the number of AI I load up.

    Ok, so I did a quick test with different builds (some reduced settings due to only having 4 GB GPU):

    v1117:

    Sebring full layout 0 AI: VRAM 1750 MB, RAM 7400 MB, page file 15000 MB
    Sebring full layout 10 AI: VRAM 2250 MB, RAM 8000 MB, page file 16000 MB

    Nordschleife combined layout 0 AI: VRAM 3800 MB, RAM 9700 MB, page file 19500 MB
    Nordschleife combined layout 10 AI: VRAM 4000 MB (maxed), RAM 10700 MB, page file 20000 MB

    v1116: same
    v1115: same

    I skipped Sebring and only tested Nordschleife with v1116 and v1115, but results were identical. Obviously Sebring still consumes little VRAM, so there doesn't seem to be any issue with the build. Nordschleife is quite heavy, in particular combined and 24h layout. The workaround is basically to lower circuit, opponent and texture detail settings, the last one mainly.

    @stonec Nords needs 6Giga Vram for sure to avoid frame drops
    even if MSI afterburner says that you use 3950 video ram it still drops the frames cause it needs a lot of video ram
    indeed lowering Track and texture detail we end up using 3500 Vram or something like this.

    It was. rFactor2 used the full 8Gb of the Vram of my 1070 with the Nords from day1

    that may be so. Wasnt really fast esp. in GP part . But the new version is unplayable with my settings, in pits i am < 25fps with 40AI. I am not a big NOS Fan, so its not a big deal for me, but that track shouldn't be so demanding with that visuals. They could cut the tree height by 50% to save some frames :D

    No endurance racing series starts from a standing start, they do rolling starts and all the cars are geared for that, exactly as in real life.

    There is an issue, because something changed, but in the interest of narrowing down the problem, can anyone confirm this helps? -->

    I think it's key because all of my other settings are medium or lower.

    We UNDERSTAND that these cars all compete with rolling starts. But pitstops, crashes, some penalties, all require starting from a standstill. What we are trying to explain is that these cars were changed. They did not blip up and blip down the rev range so quickly. They LM24hr drivers criticized the BOP from an handling viewpoint almost immediately. This engine inertia issue MAY have contributed to those handling complaints since the off throttle rpms drop so quickly it may have been engine/tranny caused weight shift but felt like chassis imbalance. Compare the current GTE engine rev rate to any of the 3rd party cars, URD, Enduroracers, none of those have such an immediate climb and fall of rpms. (and neither did these S397 DLC cars either, until that pre LM24hr BOP.)

    This about sums it all up. Marcel said he was going to address it this week. Hopefully he keeps his word.

    So actually a rehash of what he said last week with added sentence just to make it seem like some effort was done. Ok... I guess. Brave new world!
