--- Comment #2 from Ulrich Gemkow ulrich.gemkow@ikr.uni-stuttgart.de --- Thanks! Unfortunately the app is very old and not HIDPI aware. Setting the value in the registry as described in the bug report you mentioned makes the app unusable.
The "high CPU load" problem makes setting the graphics resolution for such programs in wine 10.0 unusable. And "high load" means "eating" the whole (rather powerful) CPU - the cooler goes to max speed.
In the past (before the HIDPI changes, i.e. in Win 9) setting the graphics resolutions to a higher value worked and gave benefits also for old apps.
So my question is - is there a possiblity to revert to the old behavior at least until the new implementation is complete?
Maybe I misunderstand things completely - then sorry!
... And thanks for your great work in wine!
