Full Sync versus Half Sync

Just noticed the difference with CPU and GPU utilization when running Trainz at full sync versus half sync.

On my system running at full sync shows both the CPU and GPU utilization rates are about 50% higher then when running at half sync. There is also about a 20% increase in the running temperature of the GPU.

I normally run Trainz at half sync but was doing some testing on another issue and discovered this.

I guess this is normal, but why?
 
Half Sync is Half of the refresh rates that may have set in the Trainz settings tab.
I have mine set at 60FPS at 1920 x 1080 Rez. Full Sync.
If I turn on Half Sync the Trainz will run at 30FPS, less power needed to run set to Half, but it has Micro Stutters. Than is why I use the full Sync method.
 
I usually run at half because I mostly build routes and sessions. When I want a video I switch to full. Running on laptops heat is an issue.
