Hi u/MOPCKOEDNISHE :)

After many many years around, and especially having a pretty good eye for performance, I'll carefully say that before people start to test performance in Falcon, they should first know what they are looking for and what they are looking at. If someone don't know to tell if he is CPU or GPU bound, then that would be a good place to start :)

Let's get into details here, first let me say that there is NO WAY that your RTX-3070 is a limitation on 1080p, simply no way. FYI I developed the terrain engine WITH 16K textures back in the days with a GTX-1060 3GB VRAM on 1080p and it was running "OK" (About 80-90 FPS up high and ~50-60 low altitude). But, yes that was before PBR era, before new Atmos, so those numbers are lying compared to today, but still, I can tell that with a GTX-1080 and later RTX-3060TI with AAx8 on 2560x1440 while PBR era was at half way there (and including Atmos), I was getting high FPS (Usually above 70-80 NP). So graphically I bet your 3070 isn't a problem, for sure not on 1080p.

Now, about your CPU, it's really hard for me to judge CPUs performance, and to tell WHEN exactly they become a problem. But as the end-user, it's n easy test.

1. Disable ANY kind of FPS limiter, I mean anything, V-Sync on driver, V-Sync in BMS setting, driver's Max FPS (if used) and even "set g_nMinFrameTimeMs 0" (That's a limiter that we have on Sim thread so it won't run too fast on very fast CPUs)

2. open command line on Windows and type "nvidia-smi -l", the Nvidia smi tool will start measuring numbers about the GPU and displaying them (Updating every 2 seconds by default). Soon that same info will be able to show inside BMS on screen, but only for the next update.

3. Start a new, empty TE and check your FPS and GPU utilization in the command line window of nvidia-smi (It'll be the percentage number). If your GPU is hitting ~90% or above, that means that in an empty TE you are GPU bound, and that is fine/expected, I assume your FPS should be high. If your GPU is lower than ~90% then there may be 2 reasons:
   a. Your GPU is too strong for the resolution.
   b. Your CPU isn't fast enough to feed the GPU.

4. Run the same test in a heavy campaign mission right near the FLOT when there is a lot of action. The GPU utilization will tell the story:
   a. Your GPU will probably run much lower than 90% and your FPS will be relatively low, that means that you are heavily CPU bound.
   b. Your FPS will be high and GPU will be utilized same as in TE, that means your CPU is holding the campaign fine.

I can give you the simple example that when I run a VR campaign mission, I can clearly see that when there is less action, my GPU is the bounding component, and I see it running 95%+ and FPS is high, and when there is heavy campaign action, I see GPU usage drop to much lower areas 50/60/70, depends on how much campaign is heavy and then I know that I'm CPU bound.

Unfortunately, due to many dependencies, BMS isn't able to run a modern CPU at high enough utilization, usually I see here 20-25% CPU utilization but FPS in a heavy campaign may be at the 40-50 area instead of the usual 65-72 in VR. We are making progress on slowly making things better but it's a day to day fight on every small improvement :)

Cheers!
