Our recently deployed Hotfix did not fix the ongoing issues with blurry textures and decreased overall performance on some hardware configurations.
However we are happy to announce that we have tracked down a bigger underlying problem and are already working on another hotfix.
Unfortunately the solution requires us to re-build lots of data for all our maps, which is an automated but sadly lengthy process.
We estimate that all maps will be fixed in 3-4 days. Until then we might be able to hotfix levels like Feitoria earlier, as these issues are most apparent on the bigger maps.
Once again, sorry for the inconvenience.
