Below are the settings that I and many others have found to be the best possible graphics settings to attain the clearest visuals in Aces High with VR. Without getting into details, many settings and post-processing which look great on flat monitors actually look worse in VR because you are so close to the image. Even if you have the hardware, increasing every graphics setting does more harm than good in VR visually.
The goal here with these settings is to get as much clarity as possible, reducing blurred distances, shimmering trees, and things just looking off and out of focus. Achieving more crisp visuals in Aces High with VR actually requires reducing settings, which will give the added bonus of increasing performance too.
Below are the settings one-by-one, attached are screenshots of the various settings both in the control panel AND in-game. For those of you without Nvidia cards, just use the AMD equivalent setting.
