We're on Unreal 5- it's certainly not a perfect engine and has plenty of issues, but it's a decent option all things considered.
Ah. Finally maybe I can have important questions answered about the future of graphics in games.
1) Are you implementing hardware raytracing or software RT (Lumen) or both?
2) Is it conceivable that at some point, pre-baked lighting will become a thing of the past in almost every game from medium to large game studios? I understand that indie and smaller studios may not have much use for complex graphics in their games.
3) How long is 8GB VRAM going to remain acceptable at 1080p?
4) Is UE5 TSR good enough that a developer can just use that and not bother about supporting FSR, DLSS and XeSS?
5) How hard is MacOS development using UE5? Is it a matter of just loading the project on a Mac, changing some settings and maybe some code and the game achieves native performance and able to use the maximum capabilities of Apple's M1/M2/M3 GPU cores?
6) What do programmers in game studios do in their spare time? After finishing the main game engine and tooling work, I suppose they don't have much left to do so what do they do with that available time? R&D for future direction? Messing around with SDKs of other platforms to see how well the game will run on them and see if it can be commercially viable to release the game on those platforms?
7) Suppose Tim Sweeney wakes up tomorrow and suddenly has the kind of crazy milking thoughts that destroyed developers' confidence in the Unity game engine. What options would your studio have to fall back to? What would be the damage in terms of dollars or amount of time wasted in porting the game to a new engine?
8) Is it possible to design a game to be engine agnostic?
