Then you might want to change your 486DX for a new computer, VAM2 Tech Alpha runs at 750fps at top speed here
People should really understand this: over 80% of the games today are not running badly because of the renderer, but because of the logic which mostly includes path finding an AI. You can have twenty 4090 in your PC, if those GPUs are waiting for the CPU bottlenecked by NPC computation, you will still have a low framerate.
VAM is meant to be a simulation. And a top notch one.
VAM 2 WILL fuck up your GPU and CPU because it will try to push the boundaries of visual fidelity and physics further. You will still get scenes that run very badly because (most) people releasing content are pretty much clueless about proper optimization.
On the other hand, meshed is planning on having subdivisions options as it is mentionned on the patreon, which will allow creators that knows what they are doing to release scenes that could be optimized for more NPCs.
Finally: you can't ask for a game to break the visual and physical simulation barriers AND have it run at 250fps at 8K in VR. We don't have the tech nor the hardware to do that. DLSS and all those upscaling techniques exists ONLY because we don't have the hardware to compute all the fancy features in realtime.
So no, you won't have a VAM 2, running at 250fps, in a swinger party with 30 people, all animated, physically accurate, and fluid simulation all over the floor.
