My setup is:
AMD FX 6300 (six core)
Radeon R9 270x (2 GB)
Zwift takes the high profile for my setup.
First problem is, that the fps rate is 60% of time around 60fps but it drops around every 30 sec. to around 17 fps for a period of about 10s. (Watopia)
For New york it is the same but with lower fps.
In this cases the gpu usage drops from 80 to 40%.
Anotzher thing is, that if I change the resolution in the game, the grafics quality changes according the resolution, but it has absolute no effect on the fps. Restarting the game has also no effect.
Thos means 20-60 fps in 1440p and 20-40 fps in 576p.
It is a freshly installed Win10 pro, With up to date drivers for the graphics adapter.
Does anybody have an idea?
