Is Euro Truck Simulator 2 more CPU Intensive or GPU Intensive?

Solution
I have both ETS2 and ATS. Both are heavily GPU bound, but when you start doing add-ons (weather enhancements, vehicles, interior dashboards, extended maps, etc.) the CPU starts becoming important too (my observation when running MSI Afterburner in the background and watching the GPU vs. CPU % usage).

^^Correct like most any game (the higher the resolution and quality settings, the more the GPU matters than the CPU). But his question is if ETS2 is more CPU or GPU bound out of the gate. Unless one is running a 720p laptop on integrated graphics with no details cranked up, it's more GPU bound.

I've done a lot of tests on ETS2 and ATS at various resolutions from 1680x1050 to 2560x1440 (actual different monitors, not merely in game settings) as well as with various CPU speeds from stock (3.9GHz Turbo single core) to 4.7GHz four core. I'm also a heavy modder, so that makes a difference as well on how the CPU reacts as stated previously. Overclocking the CPU helps at 1080p a lot more than at 1440p. Again, nothing new there when it comes to how games in general react to your settings.
