WineD3D without workaround

Hello guys,

I can confirm that it's an issue with Ryzen CPU unfortunately. 
A workaround has been found on the DXVK discord and the solution is to disable
the half of all cores. 

For me with my Ryzen 1600 and her 12 cpus, i must to disable the 6 last cpus by
these commands :

echo 0 > /sys/devices/system/cpu/cpu6/online
echo 0 > /sys/devices/system/cpu/cpu7/online
echo 0 > /sys/devices/system/cpu/cpu8/online
echo 0 > /sys/devices/system/cpu/cpu9/online
echo 0 > /sys/devices/system/cpu/cpu10/online
echo 0 > /sys/devices/system/cpu/cpu11/online

Now, i attach all screenshots with Wined3d, Gallium-Nine, DXVK with and without
the workaround.

The difference is not great with wined3d but with Nine and DXVK, it's very good
