Thanks Phrog. An interesting question. The short answer is "I don't know." 😀
The G3000 Vision Jet in MSFS is TA Only. Doesn't generate any RAs. Does generate a flashing yellow "Traffic" alert on the PFD for targets of potential concern but I dont know what the criteria is other than "pretty close." I've only seen one a couple of times and that was landing with an AI aircraft holding short for the runway or on an adjacent taxiway.
It matters in the sense that there's a better way to do it, which will improve picture quality.
Instead of changing the in-game resolution, I suggest you keep it at the native monitor resolution. Then, adjust the render scale to less than 100%, around 55% if you want the game to render at 1080p. What this does is that the game will render at a lower resolution and then scaled up with a fancy algorithm to look reasonable. You can then also play with the AMD shaperpening slider in the game (available on all vendor cards, not just AMD).
If you want to try it, you can also use the DX12 beta version of the game, which will enable the AMD FSR option (available on nVidia cards too). In my experience it looks better than the render scaling setting, but the DX12 beta can be less stable. FYI, if you want to try this, the setting is under the Anti-Aliasing settings IF you enable the DX12 Beta. If you have an RTX GPU, you can try DLSS too.
Out of curiosity, what are your system specs?
I have a newer LG 32 inch gaming monitor that has a native resolution of 2560x1440, it has a wonderful picture quality.
For some reason, I thought the resolution in the MSFS settings should be set to the same 2560x1440. I have a mid grade computer and had a fairly good looking picture but the sliders had to be set in the low - medium range.
Out of curiosity, I set the msfs resolution to 1920 x 1080 and picked up another 10-12 FPS. I'm going to play with turning things up.
Does it matter in any way if the screen resolution and the msfs resolution are set differenty? I have a feeling it shouldn't matter, but thought I would ask.
Ah, the search only found repaints. Alpha India Group have an FSX-compatible model, you'll need to register on their forums and then search for TFS A380-800, unless this link works for you: https://www.alpha-india.net/forums/index.php?topic=25437.0
