Low FPS when looking at objects from afar

Hi, I’m currently having issues with only one section of my level that is receiving low fps. I seem to only get ~35fps in the Oculus (causing it to either jitter or blur to the point it looks like double vision when I’m moving my head) when I look at the section from afar, however when I move close enough the fps would jump back to ~75fps and would look fine. What could be the factors contributing to the low fps?

Hi

As Anatoliy said ^. You will need to adjust your LOD to fix this. IF you LOD is too high, then it will render everything to level. So instead of trying to Render 500 Meshes for example as Level, when further away, it is trying to Render 2000 Meshes at detail, thus lowering your FPS.

Hi slam937. Its video card can’t calculate faster. Difference between two images what you see, in first closer to but geometry not sow many in viewport. But in second image you see much more geometries and video must calculate more details. To this fixing try use LODs geometry and materials, and try retopology all geometry to remove unneeded (vertex, edges and faces)

Hi Anatoliy and , thank you for your informative replies! I will definitely look into creating the LOD now, but just a quick question - would I need to create LOD for all the static meshes in the scene?

Hi slam937. Yep for all static meshes. But this is very big work. First try simplify all geometry (topology) and materials without LOSs . And try check fps if result will not good, try setup Engine Scalability settings: anti-aliasing, shadows resolution and e.t.c. Only if after all that you can not take nice quality and fast fps you need create LODs. And Try start from big meshes, big i mean with geometry where have many polygons. In ideally you need create for all geometry LOD but if you have for this. This is not strong rules, i just write how i working with this.

p.s.
And if it will help you try testing every on pc with not strong hardware i trying testing on middle powerful pc. After that you can understand how your game will work on standart(middle) platform.
