August 18, 20205 yr I loaded up Developer Mode in the Options to take a look at my FPS and noticed red text stating the above, "Limited by GPU". So my question is, does anyone know if this means my GTX1070 is holding back the sim at my "High" settings (which the sim recommended and set) or are they suggesting some Nvidia Control Panel software setting is locking down the frame rate? I haven't set any per-program settings in the card for FS so I suspect it's the former and after the 3000 Ampere cards hit I'll be grabbing one (likely a 3070), but would prefer to make the best of things with this for now. Thanks. i7 8700K @4Ghz, EVGA RTX3080 Ultra, 32GB RAM, Two 2K displays. Alpha Yoke, Bravo Throttle Quadrant, CH Pedals.
August 25, 20205 yr I am getting this as well. I've seen other videos with Dev Settings on stating "limited by Main Thread". I'd like to know what these notifications actually mean. Asus ROG STRIX GeForce RTX 2080TI MEG ACE MSI board with 32 Gig of Patriot Steel Mem (running 3800) and core i7-9700K.
August 25, 20205 yr Well, it depends on your point of view. It's not necessarily indicating a problem...there is always a bottleneck somewhere. Always. Generally speaking, the bottleneck is either the CPU or the GPU and it's simply telling you which one is the bottleneck. If it says "Limited by Main Thread" then it's telling you the bottleneck is CPU. I always prefer that the bottleneck be the GPU because that technology tends to advance much more rapidly...new generational leaps in performance almost every single year. CPU performance increases tend to happen more slowly and changing out your CPU is much harder (I rarely bother without building a whole new PC). Short answer, if it says you're "Limited by GPU" and you have a GTX1070, then you can improve things by buying a better GPU (or reducing settings). However, if it says this and you already have an RTX 2080 Ti then there's not much you can do until the RTX 3080 Ti comes out. Edited August 25, 20205 yr by nbhall68 More clarity
August 25, 20205 yr You want to be limited by GPU rather than CPU. This would tell me your CPU is able to effectively pass on enough for your GPU to work at 100%. If your CPU was at 70%+ and your GPU was at like 50-60 or so and you were still getting bad performance, then that would tell me your CPU was bottlenecking. (You don’t want this).
October 11, 20205 yr I am getting "Limited by GPU" as well. I am very surprised as I've always thought my CPU (4790K stock) was the bottleneck to my GPU (GTX1070). MSI afterburner reports CPU at around 50% and my GPU is typically around 90-99% so I guess that makes sense. I'm getting about 25-35 FPS depending on were I'm flying. I was going to upgrade my CPU/MB/RAM and keep my 1070, but now I guess I should just get a new GPU instead, and get another year out of the 4790K.

Or continue flying happily at 25-35 FPS without paying top dollar for a mega video card 🙂 Bert
