Bart's Laptop Specs
HP Spectre x360
CPU: Intel Core i7-7500U @ 2.7 GHz (2 cores)
GPU: Intel HD Graphics 620
RAM: 16 GB
Game Tested
All tests performed with Scud Race at 1024x768, windowed mode. I played 2 laps on the daytime beginner track.
It was extremely challenging to run comparable performance trials. My laptop CPU is constantly pegged by stupid background services (Windows Installer, Antimalware Service Executable, Windows Malware Remover, telemetry, Chrome, etc., etc.) I've never invested much time in optimizing this machine. These things cause overheating and, evidently, CPU throttling, which can deal a 10+ FPS hit to Supermodel. For testing purposes, I closed all visible applications, enabled Airplane Mode (in hopes of choking off telemetry services and Windows update), and then spent several minutes observing Task Manager and playing whack-a-mole with the various CPU hogs that would pop up. Once things seemed stable and the CPU was idle, I was able to run Supermodel.
Results
New engine, no quad rendering: ~50-60 fps (dipped below 50 on first lap, maintained 60 most of the time thereafter with a dip to low 50's on one segment)
New engine, quad rendering: ~40-48 fps
Legacy engine: 60fps
CPU usage was about 35-40%, so not very demanding.
I'm not sure which of the Model 3 game is hardest on the rendering engine but it's definitely not Scud Race (or Daytona 2, which ran similarly well). I expect that some of the Step 2.x titles will perform a bit worse.
Bottom Line
Legacy engine works great but looks hideous (primarily because of the colors; its other shortcomings may be tolerable depending on which games you play). The new engine, sans quad rendering, actually runs decently well but there are noticeable performance hiccups. The laptop gets hot in either case. It sounds like you're eyeing a similar machine so I expect performance to be comparable.
For a quick play every now and then, it's acceptable. If you want to play for more than 10 or 15 minutes at a time, I would invest in something closer to a gaming laptop.
I wonder if it's worth spending a little time fixing the shading model in the legacy engine?
