This is an optimization patch for the PDL (Portsmouth Direct Line) Waterloo to Portsmouth route in Train Simulator.

=========================
WHAT THIS PATCH AIMS TO DO
=========================

– Eliminate OOMs, especially when starting at Waterloo
– Improve general frame rates by 30-70%

=========================
WHAT THIS PATCH CANNOT DO
=========================

– The patch cannot eliminate tile loading spikes in PDL, where FPS drop for 1-2 secs.
– Eliminate OOMs and improve FPS if your settings are simply too high for the route.

On investigating the PDL route I found that it is certainly one of the most dense and object-filled routes in TS. There are AI branch lines (eg. to Norbiton) that the user will probably never see, that are packed with resource-demanding assets. This leads to the new tile loading spike (drop in FLS) being much higher in PDL that it is in almost any other route. I have removed some of these assets, along with the main bulk of the project which was to remove very high demand 3D “near” trees, where they have been excessively or inappropriately used. A tweak to the lighting at Waterloo has also drasticallly improved performance and stability at that station.

Please read the README-INSTALL, and please ensure you BACK UP your current PDL folder, before extracting my patch files into it.

Enjoy!
