This game runs fine on most systems.
On my 16GB, GTX 1070, i5-7600k
- I get a solid 55-60 FPS capped (only drops when assets are loading in.)
On my 4GB, i3-6600m, Intel Chipset
- I dip to around 30 - 40 in battles.
The game only uses about 2-3GBs of RAM, but the CPU skyrockets during battles, jobs, etc. even on my gaming rig.
CPU seems to be the biggest user here, which makes sense since RPGMaker MV is a Java based program. Plus, the game never uses more than 5% of my GPU even on max settings.
And yes, RPGMaker MV requires no RTP. The necessary assets are already in the game files.
