I just tried out Robocop. I'm playing at 1440p using max settings, Lumen enabled, Optiscaler FSR4, FSR4 'Quality', in-game FSR FG, and in Adrenaline menu FSR4, Anti-Lag, and Enhanced Sync enabled, along with FreeSync forced 'On'. Getting 100fps+ without FG, and 200fps+ with FG. This runs extremely smooth, even with a mouse. Pure butter.
At first it was running ok, but looked a little weird, like blurry, and not perfectly smooth. I figured out that Optiscaler automatically enabled OptiFG, so it was running 2 instances of Frame Generation at the same time.

Now I'm just using in-game FSR FG. Looks way better and has much better input latency. Something like that happened with R&C Rift Apart when I first ran it, too. Frame rate was insanely high like 300-400fps, but it was stuttering.Then I realized it was running AFMF and FSR FG on top of each other. That's a slightly annoying quirk of dealing with AMD. I'm learning the ropes now so everything is going smoothly. Hoping for more native FSR 3.1 or FSR 4 officially supported games in the near future.
Also learned that some games like Cyberpunk have issues with crashing with Optiscaler on Win10. There's a workaround for it using the more recent Nightly Builds. I used it on Robocop as well:
As a side note, even unofficial Optiscaler FSR 4 looks leagues better than old FSR 3. This is 'Performance' preset:

*Sorry for the info dump. It's not specifically in regards to our FSR FG testing. I just figured anybody buying a 9070-series should brush up on this, since this is how we get FSR 4 until there's more official implementations.
