Yet another DCS shaders performance update is available on the DCS forums here.

Its compatible with 2.5.6.47224 beta and fixes a few issues that have accumulated over time. There is also a setting to keep bloom enabled, it seems to have a much smaller performance hit noways.

It also contains a new feature: Supersampling for the albedo (diffuse) textures. It is a very performance-cheap way to get improved clarity especially for the cockpit labels and stuff. So instead of having to supersample the entire rendered scene to get more sharpness, it will sample the diffuse texture multiple times.

The difference looks like this:

Even with just 2x sampling the text labels (like “FIRE EXTGH”) are much sharper and its performance hit is very neglible, almost any GPU tha runs DCS in VR probably can do 4x without any noticeable hit. It looks even better in the headset than in the screenshot. With it its possible to turn down the pixel density quite a bit without getting a blurry cockpit, and then use the performance headroom to do 4xMSAA for smoother geometry edges.

It can be controlled with _HMD.hlsl setting ENABLE_DIFFUSE_SS, the default is 4x.
