Build: 1.5.3 3390 Mode: Survival Mode: Single player MODIFIED PLAYFIELDS: Yes. Reforged Eden but can also be seen in the base game. RE seems to have higher spawn rates of foot patrols so its easier to notice but that could just be my luck. Reproducibility: Always Severity: Critical Type: NPC AI, Spawning, Performance Summary: Possible leak with NPC spawning/AI Description: When visiting areas that are heavily populated by NPCs such as planetary faction territory I have noticed a heavy hit to my frame rate. The strange part is that the low frame rate persists even after leaving the area and the POIs and NPCs supposedly unload. The frame lose isn't that bad while standing still (2-5) but is VERY extreme (up to 30!!!) while moving. Moving into another populated area causes further loss of frame rate. Only by leaving the playfield can I get my frame rate back up to a stable 60. I can then return to the playfield and the frame rate will remain stable until I visit a populated area again. Steps to Reproduce: Start a new survival game. Turn on the frame monitor. Turn on God Mode or spawn an SV so you can move around the playfield quickly. Travel to the middle of Polaris territory and note the frame rate. Travel far into the wilderness so that everything in Polaris territory unloads while monitoring the frame rate. Travel to the middle of Talon territory and note the frame rate. Travel far into the wilderness so that everything in Talon territory unloads while monitoring the frame rate. STOP MOVING and note the frame rate. TAP any directional key to move 1 or 2 meters while monitoring the frame rate. Moving up/down has no effect; it hast to directional movement. My specs CPU:i9 9820x (no OC) MB: ASUS WS X299 SAGE RAM: 32 GB DDR4 GPU: EVGA GTX 1070 PSU: 850 watts OS: Windows 10 Pro Drivers are all up to date. Games frame rate is capped at 60. === Edit === I decided to open up the task manager while moving around in game and discoverd something interesting: while standing still my GUP utilization hovers between 70 and 76 percent during my current play session but if I move GUP utilization falls to between 48 and 54 percent. Yes, that's right, GUP utilization goes DOWN while walking around instead of standing still.
