The CA is much improved for me. Now I have to revert to using the non CA enhanced .dll files.
The tracking seems much more buggy though and I am having compatibility issues as well. If the CA is not a huge problem for you (it was for me) I’m not sure I would recommend the upgrade.
vorpX has its own chromatic aberration correction BTW. It should have been enabled per defaut on DK2, but isn’t in most games unfortunately.
You can enable it on the display page of the ingame menu. There also is a software fix for the OLED black smear, which is quite useful in high contrast games.
