Interesting GPU/CPU Usage

I noticed that too. The VRAM gets fully stretched within seconds after entering the scene. As far as I understood the VRAM cache gets cleared automatically to ensure that there is always enough free VRAM to run the application and to avoid that kind of bottleneck. IMO this does not work correctly as the VRAM is always around 100% workload.

No it is not Icebear, but you must have lots of it

It appears the max VRAM used was 2,1Gb over London (your mileage may vary depending on the resolution you play I presume).

So, if your card has 1Gb VRAM you need to be very consious on how much graphics detail and how heavy the map is you fly on.

My 1,3Gb VRAM makes many maps playable but I immediately notice when the limit is reached (halved fps).

PS. Antartica!? Say hi to the icebears from me, if you find them
