    Hello, I have a i7 4790k and I can barely reach 50 fps on the new Italy map, my graphic card is running at 50% so I guess my CPU is bottlenecking, but the i7 4790k is very good at single core performance.

    I noticed that changing the graphics settings does not change anything to my fps, even SSAO, it only change my graphic card usage.

    I tried, it give me about 2-10 more fps but almost doesn't change anything to my graphic card usage (still <60%)

    Without dynamic reflections : 47 fps ; CPU usage 35% ; GC usage 55%
    With dynamic reflections (all max except update rate at minimum) : 43 fps ; CPU usage 36% ; GC usage 56%

    I have the same CPU, but a 1070.
    Similar performance, 50FPS near/in the city, and 60FPS away from it.

    Seems on par.

    I see, so I guess this map is too big for actual cpus :/

    Like any new maps we release, performance will get better as we go.
    We have more optimization in plans.

    now i realize i dont have that cpu but i average around 45ish fps aswell to mid 50s depending on where i am and what way im looking i have a Ryzen 7 1700x and a1080ti and about 397mods installed (not sure how much preformance is lost on that many mods)

    Overclock your CPU, my i5 4690k at 4.4GHz hasn't dropped a single frame on the italy map. Always a fluid 60FPS. It's the best map for me :)

    I have light rays, ssao and dynamic reflections off, slowest fps is around 56-58fps, i7-6700 and gtx1080, but 16GB DDR4 2666Mhz CL14 which might help a bit as overall there should not be too much of performance difference between stock 4790K and 6700 non K

    Background process like Microsoft Defender can cause considerable impact on performance though when CPU is pushed to limits.

    More optimizations will of course help.

    Other maps probably run a lot better now for you?

    Italy has so much stuff that it is kinda amazing how well it runs on my system.

    Some maps like grids maps almost doesn't bottleneck

    Vsync makes smoothest gameplay in this game, as long as your hardware can do over 60fps, so I'm using that and there are no real bottlenecks in game right now.

    Way game works seems to be such that more fps does not necessarily result better smoothness, but CPU load increases rapidly, GPUs are much stronger than CPUs today and I have found really lot of games having trouble feeding modern GPUs without bottlenecking CPU.

    Maybe it is kinda natural for CPU to bottleneck at higher fps then.

    I see, I would activate V-sync but I have a 144hz monitor and since I never reach 144fps excepted on grid map it's a bit useless for me ^^

    If you play full screen, you could activate adaptive vsync in nvidia control panel, there is option for half refresh rate which could be more achievable.

    I'm not sure if 144Hz monitor can do lower refresh rates? My ancient 60Hz monitor can do 50Hz and 59Hz in addition to 60Hz, then some odd interlaced ones of much lower frequency.

    Then there is fps limiter option, but at least for me that is not so great as it makes lot of stuttering from some reason, even on gridmap.

    Wish there would be freesync for everyone, I have heard it being nice, but maybe in a future we get free from these refresh rate limitations.

    Yes it can, by default it's even on 60hz I had to put it manually on 144hz. I will try this
    --- Post updated ---
    I made some test quickly and it seems that when I set "Lighting Quality" above "Lowest" it litteraly KILLS my fps I go from 75 to 45 ! So maybe some optimizations to this settings would help a lot. Maybe find a way to make the graphic card calculate this setting instead of the CPU ?
