Many thanks for your suggestions. I tried a lower res on the side screens, it gave a few FPS back, but not that much. I was not able to get Nvidia Surround mode to work however. I couldn't get the Timings match between my iMac 27" (2560 native) and my BenQ 27" (1920 native). Though the iMac has a 1920 res configuration, it has a larger pixel area and applying the BenQs' 1920 Timing parameters would just mack it go black. Bottom line is I'll have to trade my iMac for a PC. I am leaning towards an i7, 16Gb RAM, GTX-1070 8 GB + the same BenQ monitor. Please let me know if you reckon this does not suffice for a smooth 3-screen rendering, or you think this is not a future-proof enough setup. Cheers.

So 3.5GHz Intel i7 with GeForce GTX 780M 4Gb. Screens are 27" BenQ Gaming LED monitors but not 4K,. I'd obviously look at increasing P3D setting-level if switching over to a PC, so an i7 configuration with a RTX-2060 or a GTX-1070 be the way forward to comfortably run in 3-screen? (not sure if 32GB Ram is needed too?)

Many thanks for the quick reply. Fair point (I actually thought the "High-spec" would trigger some reactions but was not sure what else to call it 🙂) I will get you the details specs (i7 clock and video card) tonight but from your initial messages, I take the video card is most likely the bottle neck in a 3-screen configuration. Any idea as to what would be the right PC specs to obtain good performance in such a config?

Hi All, I am running P3D v4.3 PRO on an iMAC i7, 32Gb, 4Gb NVIDIA, 128GbSSD/1Tb via Boot Camp (with Win10 on an external 240Gb SSD). With most settings between Low and Medium, everything runs smoothly and I get 60FPS. This however collapses to 20FPS- when in multi-screen. I have Left and Right views (through View Group on 2 separate monitors off my iMac) and this seems to be killing it - though I am unable to see this necessarily reflected in GPU and CPU stats. Is this performance drop normal and is there any solution to it? Would a similar setup on a PC yield higher performance in a 3-screen configuration? The most taxing setting I have seems to be Scenery Complexity (medium) but I need a quite good terrain detail level as I use P3D as a training platform for my PPL. Other add-ons on my iMAC are ASCA, U Live Traffic and my home plate scenery. I also have a Garmin G1000 sim on a separate PC but this is through WIFI. Thanks for any help and hardware advice you could provide (happy to switch over to a PC-based setup, but I need to make sure what config to go for then).
