I cleaned out old configuration directory to start with a defined state for PlaneShift with Unreal Engine 5.1.
Default is epic for all graphics settings. This gives me 10 to 11 fps in Gugrontid on ThinkPad T14 AMD Gen 1 with AMD Ryzen 7 PRO 4750U with Radeon Graphics, Renoir, Vega 7 I believe and 32 GiB of RAM. This is too slow to be playable nicely. Cause when moving viewing direction around with left clicked mouse it often goes too far before I receive feedback on screen.
Unfortunately even with all on lowest quality it is just 20-22 fps in Gugrontid. But in Hydlaa near the Pterosaur it is even worse: Just 12-14 fps. About 20 fps is playable but still not nice, compared to the previous fps:
Before I had something between 25 and 50 fps depending on scenery with much higher settings than "low" on all gfx related options. It was not epic with all settings, but AFAIR with at least 3 out of of 6 of them. This was working nicely for me. It definitely felt snappy enough. Not all of the graphics quality options seem to have a big effect on FPS. For example texture quality does not seem to matter at all. I can just leave it at Epic.
Compared with Crystalspace based PlaneShift client this is a huge drop. After some more recent graphics driver optimizations I have between 100 and 144 fps in Gugrontid where 144 fps is current refresh rate for my external display. And its still 40-110 fps in Hydlaa. The fps variation is higher in Legacy PS.
Also startup of the game is much much slower. It takes about 1 minute before PSUnreal even likes to interact with me on startup of the client. The client window opens, PSUnreal catches mouse pointer and then I have to wait for about a minute, maybe more before I can do anything. But it seems at least the crash on exiting the client is gone.
Granted this is a laptop with onboard graphics, however much better than older on board graphics like Intel Sandybridge.
I fear that this will make it impossible for more players with older hardware to play PSUnreal with decent speed.
This is on Linux 6.2.1 kernel with Vulkan 1.3.239 and Mesa 22.3.6.
I hope performance can be improved again. I know for everyday gamers with gaming PCs it would not be an issue, but with the casual gamer and people who focus on a few (probably older) games, not using a dedicated gaming PC with dedicated graphics, or for people using a laptop with on board graphics, even if somewhat recent, it can be tough. I wonder whether graphics quality has improved with Unreal 5 or Unreal 4, i.e. whether the additional hardware demand is somewhat justified. Maybe you can give players some other options to reduce graphics quality to make Unreal 5.1 based PlaneShift more playable? I would like to avoid having to buy another machine, probably one with dedicated graphics and thus higher power consumption, to be able to play PSUnreal at a decent enough speed.
Lighting still is an issue. You already mentioned it. As before the switch between day and night still seems to be almost instantly. I just logged in again. It was day light. Within a few seconds it was pitch black in Gugrontid. Good that I have a torch in inventory at all times.
