In SH3D 6.0 the GPU load for the 3D view (only virtual visitor) is reeeeally high, strange high. In fact it's higher than in any other application, even higher than in complex 3D games or benchmark tests. It's much higher than in 5.7 or any older versions.
This is not a big issue, because the max temperature of the polaris chip is approximately 90° C and atm the actual temperature is at 55°, but it's a noisy (because of the fan) one...
Normally the temperature of the GPU is not higher than 40°.
