I’m working on a project in ver. 5.5.4 The issue we are having from the start is low fps. Our current project includes 1 small room with 1 metahuman npc and 1 first person player. We are getting between 8 fps and 20 fps.
Even when i create an empty world with just a box to sand on, a first person character and a skybox, i’m getting 18 fps when i’m looking down at that box, and 40 fps when i’m looking directly at the sky.
There seem to be no way to fix this. I looked through almost every thread that exists on low performance in unreal 5. I tried almost every suggestion offered:
Disabling Virtual shadow maps did not improve fps
Disabling Naninte did not improve fps
Disabling Lumen did not improve fps
Disabling TAA did not improve fps
Lowering quality setting from epic to low did not improve fps
Setting maximum texture size to 128 on every texture used in the scene did not improve fps
Reinstalling unreal did not improve fps
Changing Targeted RHI from DirectX 12 to DirectX 11 DID improve the performance, but only to about 70 fps on 5.5; instead of 120 fps on 5.1
After checking almost every possible thread on this issue i found this thread:
where some people are comparing the performance between older versions.
So i tried the following:
I created the first person project in 5.1.1 and 5.5.4
I added a simple fps counter widget and started the game in PIE (that is correct, i’m using PIE as i know from multiple experiences that PIE performance and final packaged game performance are almost the same)
in 5.1 i was getting 110-120 fps
in 5.5 i was getting at best 50 fps, 70 fps when i changed the RHI to DirectX 11, but occasionally i got stuck at 12 fps
Now i have to ask:
How come that the performance in 5.5. project is so much worse than the performance in 5.1. ?
What was added between these version that could have ruined the performance of the engine to this degree?
