I walked to the Pyramid, killed some Skeletons and got an Orc killed, forgot to time it, but a few Minutes at best.
Your Screenshots look very different from the actual Game, did I miss something? Are they from a newer Version?
There isn't anything there to really break yet I think, so no Bugs encountered, I could examine the Sand, I could drink Potions, click on the Ground to move, click on Items to consume them, and on Skills to (I assume) do nothing but consume Mana. You know there's a lack of Feedback on anything, since there's nothing there yet.
Still, nice to see another RPG Game being made, looking forward to what this is going to become once its more fleshed out, and there is actual Stuff there to do, and to see what Direction you're going in.
That being said, in your empty Desert with a few Skeletons, I did only get ~150-180FPS. I know Unreal takes up a massive Chunk by default, you're never going to reliably get 1000s of FPS without major optimizations, but if you're aiming for something like Kenshi or similar, with a big open (hopefully not as empty) World, lots of NPCs, and major Battles, instead of a small Party vs. a few Enemies like it is in the current State, you might want to keep an Eye out for that.
Regardless what you're doing, please make sure to not fall into the Trap of making everything bigger and vast-er, resulting in big empty Areas of Land where you just mindlessly walk through. Unless of course you're turning this into a Party based hiking Game with occassional Encounters. I'd play that, but then the Vast Areas of Land should be interesting to look at and explore.
Edit:
Forgot to mention you have Screenshake when being hit, I'd prefer it not being there with a Camera like that.
