Let's be honest with ourselves here... If you are shelling out the money for one of these rigs with something like an RTX 4090, you could NOT care less if your PC's electricity and heat costs you $22 per year vs $40 per year, or if your loop holds $0.01 of water vs $0.03.
You just care if it can provide 90FPS+ with modern VR (Reverb G2 or above) in flight simulators like DCS World, MSFS, IL2, XP12, etc. Nothing on Earth can can do this yet at great-to-max settings, especially in multiplayer DCS and MSFS.
I'm not sure why VR Flight Sims get ignored by Toms' benchmarks, they're one of the only home workloads that hardware will fail to provide an artifact free (90 FPS+) VR experience, with any available overclocked CPU\RAM. Sure VR flight simmers are a niche group, but VR simming is a single-to-two core CPU taxing workload that is on the bleeding edge as far high raw CPU performance requirements\CPU frametimes. Below 90FPS (or 80 depending on HMD) in flight sims is simply unacceptable if you notice the ASW\Motion Smoothing artifacts like most of us. ASW\MS is designed for common VR game distances of less than a 200M. Less than a 200M is nothing in a flight simulator so we get bad artifacts everywhere at less than 90 FPS.
It's just frustrating waiting for the world to catch up to our needs and all the professional hardware benchmarking sites pretending like we don't exist.
