Thanks for your suggestions! It’s strange that the preview is that much lower in performance than the source version. I would have thought it would be higher.
From your suggestions, it would appear that TSR is hands down the biggest performance killer. With my AA model set to TSR, I can’t get any better than a 25 ms/39 FPS render–even with engine scalability as low as possible. These were the results for other options:
- TAA is a massive leap to 13 ms / 75 FPS.
- FXAA and MSAA both take it to about 10.2 ms - 9.5 ms / 98 - 103 FPS depending on whether or not the volumetric clouds are in frame.
- Changing viewport resolution had no apparent effect, and scalability was surprisingly less of a hit with the different AA models (difference between high and epic is negligible).
With how big of a difference I’m observing in the change to FXAA, I’m curious about re-enabling Mesh Distance Fields and Lumen to see how big of a hit it has by comparison. I’ll have to do that later. I’m also wondering the same thing as you regarding the Metal API; it would be great to see a software engineer weigh in on this.
