[BUG] Performance issue in PTMC Research Bunker when Render depth is set higher than 40 (minimum value)

It's seems a vanilla problem, it's explain why the Render depth control reset to minimum when you load that map in vanilla versions of descent 3.
May Interplay devs noticed this but they don't have time to resolve it, only with this ugly trick reseting the render depth control to 40.

I've tested every piccuengine and the FPS drops happens in all cases, and may be caused because the render depth allow to set to 100 in this map.

For other hand, with vanilla versions the FPS works fine, because, again, the render depth are set to 40 automatically by the game when you enter to PTMC Research Bunker

Another test that I've done is trough piccuengine set render depth to 40, and the FPS works fine, but the map look bad, with those violent clipping in the near distance.

Here's a video showing pe 1.2.2 in PTMC Research Bunker

Even with Render depth set to 40 my graphic card (rtx 4070 ti sup) drops to 110~120fps.
So the problem seems be a performance vanilla engine code.

yeah this is a known problem, if the terrain seg limit ever gets hit it resets your render depth, and will be fixed with Newrender.

In the meantime turn down your terrain detail a notch or two. it sucks but the original rendering code sucks
