Matt Davies has today updated PTA to version 2.61 which means it’s now fully compatible with P3D 4.2. PTA is available to download from Simtweaks website. No new functionality is added, only compatibility.
Important to note is that this PTA 2.61 version is not compatible with earlier versions of P3D due to different shader structure. It’s ONLY if you use P3D 4.2 that you need this version.
