I’m quite new to unreal but I’ve downloaded ue5 and even an empty level with just a player start is only giving me around 20 FPS, in ue4 a simple small level I get 120fps, using ue5 I can see my gpu is at 100% via task manager. Is this a bug or just not a good enough gpu? I’ve got a rx 570 ---

Luman defaults to on and runs in software mode if you don’t have RTX. ---

So would I need to upgrade gpu or cpu? I tried turning off lumen and it made little difference ---

I also have an RX 570. And I also get very low FPS. In a test scene in UE4 with high-poly stones from Quixel, I have 160 FPS. In UE5, if I turn off the new features of Nanite (for static mesh) and Virtual Shadow Maps, I have 94 FPS. If I turn on Nanite and don’t turn on Virtual Shadow Maps, I have 110 fps. If I turn on Nanite and turn on Virtual Shadow Maps I have 35 fps. Lumen was always off. ---

You can also turn off the new project setting _Temporal Super Resolution_ to improve performance. `r.nanite 0` in the console can give you a tiny performance increase if the scene does not have any Nanite meshes. ---

> [@Greendale\_AB](#): > > `r.nanite 0` in the console can give you a tiny performance increase if the scene does not have any Nanite meshes. Interesting. If I do r.nanite 0 fps increases from 110 to 260. But in UE4 the fps is higher. ---

I haven’t seen much difference between UE4 and UE5 performance wise. I am using a 3900X and 3090 RTX. Lumen and Nanite both on. The Ancient demo PIE runs a little low FPS, that is to be expected I guess with their recommended settings. ---

With an RTX 2080 and i7-9700K the difference is huge between UE4 and UE5 with default settings: 250 vs 75 fps. ---

r.nanite 0 gave me pretty massive performance gains. I don’t think I was using Nanite so I’m not sure why It did. ---

Ok so my 3060 arrived and I just installed it, I’m now seeing around 45 FPS which is still low but probably being bottlenecked from motherboard and cpu too, it’s still double what I did have though ---

In post 10 of the initial post [Lumen GI and Reflections feedback thread - Development Discussion / Unreal Engine 5 Early Access - Unreal Engine Forums](https://forums.unrealengine.com/t/lumen-gi-and-reflections-feedback-thread/231403/10) the instruction was given > Lumen’s use of ray-traced direct lighting is tied to the use of ray-traced shadows in the scene. You can decouple this by setting the following CVar: > `r.Lumen.DirectLighting.HardwareRayTracing 0` > > However, you might opt to work without ray-traced shadows, since virtual shadow maps are the preferred method to use with Nanite assets. ---

It is very strange, I actually want to use Nanite and Lumen, but if disabling them, is such a great solution, I think I’ll stay with dynamic lights and LOD’s for a while, sadly [Next page](https://forums.unrealengine.com/t/very-low-fps/231691.md?page=2)
