Well I finally broke down and installed a SSD to try to help the PS3 cope with all characters onscreen. It was such a pain for me to target mobs that would be invisible or the lag from fates. The loading screens are now 1.5-2.5 secs tops. I haven't been able to test the more laggy fates yet, but I've done a few 8 man dungeons and my performance upgrade is noticeable. The characters(npcs) still drop out to conserve RAM from a distance, but they pop back much faster when you're close to them. I no longer run to a npc quest marker and need to wait a long time for npc to pop. This applies to fates too where you turn in supplies. I'm still going to update to the PS4, but installing a SSD was the best thing a PS3 player can do to help their performance. I thought I've give some hope out to other PS3 users who struggle to do fates. I picked up a Samsung 120GB 840 series. It's around 100 bucks if anyone is interested.
