That is definitely a mystery... for sure.
I made sure it isn't connected to the cloud and automatic updates are off also.... nothing else has changed.... apart from the negative performance, of course.
You may be right and it's a VRAM issue.... though after all this time they really should have fixed that. They really should have fixed most of these problems a long time ago and to present a patch, in whatever stage it may be advertised as, that only seems to have removed the problem than actually fixing it is worrying to say the least.... the very least.
If we consider CloD as being like a particularly difficult child, there are two options:
1) Discipline the child and adjust their behaviour
2) Send the kid into care.
One is a solution, the other a cop out..... though either way, your Sunday afternoons are a lot quieter.
This "patch" has sent the kid off to the children's home.
It wouldn't be so bad if it wasn't for the fact that this little escapade could lead to all the people I played online with jumping ship back to 1946!
