Hello! I posted how my team was able to achieve 75 fps consistently in the thread that was linked here so I’m just copy and pasting what was in that thread.
This is how we were able to get to 75fps in our level. First off kill everything in the post process settings in project settings (you can keep AO for static objects and anti aliasing)
Delete your reflection sphere.
Open couch knights and copy there post process volume over and replace yours with it.
Turn every light you have in your scene to static.
make sure to build lighting.
Launch and make sure you are in direct to rift mode (extended caps at 60)
Also we found that keeping it under 500 draw calls (250 in each eye) helps tremendously
Let me know if this helps it might just be a solution for us.
