For anyone having the flickering issue with pantyhose, gloves, and other transparent textures when using GraphicsMod/DHH: it's due to a conflict with the BetterAA plugin. If you disable BetterAA (by renaming the file extension of HS2_BetterAA.dll in the BepinEx/Plugins folder to something else like .dll_disabled), the problem will go away. This will also alleviate some of the weird checkerboard-like graphical issues other textures sometimes have when zooming out or really far in. I think the root of the issue is that Graphics/DHH are doing their own AA, and then BetterAA is doing more antialiasing on top of that, sometimes even involving TAA, so it causes weird artifacts. There's no need to have both enabled at the same time.
