is there anywhere to check how much minimum CPU spec requirement for my monogame application?
There’s no automated way, or simple equation. Mostly it’s pick a spec and try your game on that spec.
i was planing to get a PC 4 CORE CPU for game dev and virtualized to 2 individual user. So each user will get only 2 CPU Core. is that enough for game Dev? Note* each user will get 1 dedicated gpu, only CPU is sharing
This is not something that we can give an answer on. It depends on what you are doing. If it is primarily just typing code, the system requirements for Visual Studio are a 1.6GHz CPU, 1GB RAM, etc. The more cores the better for compile times and background tasks that Visual Studio runs. Graphics editing in heavy duty applications such as Photoshop may benefit far more from more cores. Try it and see. That’s the only way to be sure. There’s nothing in MonoGame that requires multi-core machines.
