Hi I’m relatively new to UE4 I’ve been create a archvis scene for VR and My file has become so slow even when running in the low settings. My project is just a single apartment so I feel as if it shouldnt that difficult to run. My workflow was, ArchiCAD & Sketchup. the file size is 7gb if that helps at all and the computer I use runs:
CPU x2 Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz, 2601 Mhz, 8 Core(s), 16 Logical Processor(s)
GPU NVIDIA GeForce GTX 1060 3GB
RAM 16GB DDR3
HD 240GB Intel 540s
Ive also tested in on my other computer which runs:
CPU i7 6700k
GPU gtx 1070
RAM 32GB DDR4
SSD Samsung 960 EVO NVMe M.2 250GB
but it runs just as slow on that. Any suggestions to why it would be running so slow? it has been as bad as 0.4 frames per second. Im tempted to start again but dont want to run into the same issue.
Also i had to play with the shadows of static meshes , some of them are set to dynamic , i started using most of them as static , same with lights which you probably already do.
Another object that i detected that costs a los of GPU power is the Planar Reflection , unfortunately i had to delete it when playing my scenario, it worked great when creating cinematics , but it absolutely dropped my fps when using the HMD , here the proof…
I changed my mirros to a very-simple material which looks like this.
The problem is that your scene is full of scene capture cubes. Scene capture cubes render a cube map every frame. You have 12 of them, rendering 6 images each, so you’re effectively rendering every frame 73 times. It’s highly unlikey you’ll ever get your scene to VR performance with even one in your scene. Move to static reflections.
