Thanks for the help man. That is a major change in memory usage (nearly 30%). Are you using the same map size as you were in substance? I believe you can adjust the scale of the maps in the substance material right. Are they the same size as the map size that you exported from substance? It would make sense, though, since their textures must dynamically update for size and quality. I’ll try it out and see if I notice any difference in 4.9. Due to the memory leak issue that we have with the plugin, we instantly go over budget by 300-400%.
