My fifth review of 4k triple screen simracing with an RTX 3090. Not surprisingly, Automobilista 2 graphic settings and performance are very similar to Project CARS 2. You can't crank the graphics to maximum and have to choose between better antialiasing or better textures.

System specs
Monitors: Dell U4320Q (4k 43" IPS, 60 Hz)
GPU: EVGA RTX 3090 FTW3 Ultra
CPU: i9-10850K @ 3.6 GHz
RAM: 32 GB

Automobilista 2 graphics settings
Alternative: Increase MSAA to Medium and change the other "Medium"s to "Low" (except Detailed Grass, Particle Level, & Particle Density)

Results
Let's get weather performance out of the way: Storm and Thunderstorm graphic performance are not going to be possible. Night with any precipitation is not possible. Everything else will stay above 60 fps with 29 AI.

Once you rule out the bad weather combinations, the RTX 3090 is just enough for triple 4k 60 Hz monitors. If you've got to have higher fps or high refresh rates at this resolution, then it will take another generation or two of video cards to get there. I'm mostly satisfied because Automobilista 2 looks pretty good at Medium, even though slightly disappointed by the limitations of weather & night performance.

Thank you for that write up.
I thought I was in the minority playing on a single 4K 27" 60Hz monitor with graphics maxed out, but triple 4K is absolutely crazy !
For better performance, it would be interesting if the game allowed you to use 1080p on the side monitors that your RTX would upscale to 4K using integer scaling. Or DLSS but that's a pipe dream.

Holy Moly :confused:...even the 3090 is brought to it's knees slightly with Triple 4K, thanks for taking the time to post this info ;):cool:.
I did think of upgrading to Triple 4K for getting the most out of taking Screen Shots, but this has shown me that the top Graphics Cards are not quite powerful enough as yet to have everything on Ultra for maximum image quality that I would prefer for taking screen shots :(:).

The aliasing in this engine is really bad. Even high resolutions don't seem to alleviate it. In the end its either good performance or anti-aliasing. If I even think about turning on MSAA my frame rate plummets (VR). I think Nurburgring needs a couple of optimisation passes as well tbh.

How much VRAM is required for triple 4K?

There's a lot of "it depends" because different games managed VRAM differently. Most VRAM used is experienced in rF2 at Nurburgring Combined with 42 AI: 12+ GB. If you were to go past 42 AI, it's another 600 MB per car.

For AMS2, it stops requesting at 6.351 GB and AMS2 does its own paging rather than continuing to request more... most sims have similar limits, though I think ACC goes to 8 GB.

Now that I know what works, I'll be capping fps. The 3090 runs cool enough in my case, but maybe I can save a few degrees.
