UE 5.3.2 FPS limit bug

Hello everyone!

I’ve encountered some issues in Unreal Engine 5 related to FPS limitation. It seems like there’s an implicit cap on frame rate, and I’m seeking advice or hints on how to address it.

I’m working on a project in Unreal Engine 5 and have noticed that despite having powerful hardware and optimization, the frame rate gets stuck at a certain level. I’ve already tried adjusting t.MaxFPS command, but to no avail. The limit seems to be around 120 FPS. I even attempted to integrate DLSS for performance enhancement, but the issue persists.

Furthermore, I’ve observed that this low FPS occurs even on an empty scene. I’m wondering whether this could be a bug within Unreal Engine 5 or if there’s a limit imposed by my graphics card (RTX 4070).

Perhaps someone has encountered a similar issue or has experience with adjusting frame rate settings in Unreal Engine 5? I would be grateful for any advice or pointers that can help me figure out this situation.

Thank you!

Hi, try disable vsync with r.vsync 0 and check Framerate settings in Project Settings - Engine - General Settings

same here, on 5.3.2. Made sure I have these:

r.vsync=0
bSmoothFrameRate=False

but it fixes it when I add f.e

t.MaxFPS 300
