FS 2020 has released it's system specs. But if you want RAY-TRACING then you'll have to invest in an RTX level GFX card on the NVIDIA side. While I've heard that GTX 1080Ti can technically do RT, it's not optimized for it and may not work correctly. RT is what will make the final look. While many sims use PBR, I think FS2020 is the first to use RT to calculate lights angular reflectivity/refractivity/shadows when used within PBR on a scale like this. Ironic, I mentioned Ray-Tracing sometime last year or the tail end of 2018, IIRC, and was laughed to scorn about it making an appearance in the next FS or P3D iteration (can't recall that part). But, I think even RTX 2060 will do the job. Certainly RTX 2070. Anything higher, of course...
Heyyy.. Its wonderful too see you
..
Here's my thing on ray tracing..
It's too much of a fad right now to be worth following..
Microsoft has historically focused on CPU throughput, not GPU. Alll through FlightSim and P3D, your GPU was mostly just along for the ride.. Now we have ray tracing and everyone is in love with the new girl on the block.. Yes! It's been out for a few years, but it hasnt become a household utility yet. It's still in the realm of Bearded Ladies, Snake Women and the Circus side show.. Yeah sure, Microsoft is going to push this new technology and attempt to make it a household name, but are people really going to take it seriously at five hundred dollars a board, during the highest global unemployment rate ever recorded??? Ray tracing is Caviar in a meat and potatoes world. Give it a few years and lets deal with this attempt at global domination we're currently experiencing. The new girl on the block may be cute and sexy, but she cant cook or clean yet and we need cooks and cleaners with a solid history and a good backbone more than we need fantasies of our nights in bed with the new girl..
I personally will not live long enough to see the full benefits of ray tracing come to fruition. Thats not speculation, thats scientific fact, so for me, my little MSI 1070 Seahawk delivers amazing results when teamed with an AMD Ryzen and a moderate amount of ram ( 59 FPS solid in P3DV4.5 fully maxxed out. In X-Plane, not quite that high depending on the aircraft ). FS2020 will look fantastic. Microsoft may be the scum of the earth, but they arent slouches when it comes to making a sell-able product.. It'll look plenty fine to my old worn out eyes..
My biggest concern with FS2020, is that with data streaming in from scenery, meteorological sources, scenery servers and the like, Your not going to need ray tracing, Your going to need a bloody threadripper that can parallel process all of it.. Got an extra 2300 dollars laying around for a new CPU????
