Hi Maxgtp,
PVC is just one of the final optimizations i needed to complete.
Others included,
-triangle count reduction & LOD
-Texture resolution reduction
-Culling & max draw distance
-Disable shadows and collision where not needed
-Particle systems optimization.
-Replace all materials with mat inst.
-Eliminate/Reduced dependency on Event ticks
-BP Optimization and Reducing variable usage
-Merge actors and material slots.
-Disable everything that is not in use
-Memory usage
and a ton more… Pretty much every aspect has to be optimized and each is a world of its own.
