+// 3D Object culling (e.g. buildings)
+// Culling is checked via a VU microprogram, which is called from the EE via SimDispChk at 130D00.
+// A condition flag is then checked in DispChkEnd at 130D10.
+// VU disasm is lost on me so this is a bit of a shot in the dark but this seems to create more conservative culling
+// without killing performance (as would be experienced by just removing the cull check on the CPU altogether)
