+[Improved Performance]
+author=Souzooka
+description=Improves performance while camera is facing the sun, slight accuracy compromise
+
+// Jump to code cave (believed to be unused Sony SDK function)
+// instead of doing sun culling collision check, which is very slow
+patch=0,EE,20161D78,extended,0C0659EA
+
+// Only call the sun cull collision check once every 4 frames (15 times/second),
+// improving behavior and also pacing with minor frame latency
