You m8ght be able to but gameplay will probably not be the best
But how many fps will it work with?
Impossible to answer without knowing the card. The VRAM only indirectly affects the power of the GPU - it's a bit like asking how powerful a car with a 16-gallon gas tank is. You'll have to identify the specific card for anyone to give any kind of answer. Even then, an early-access game with no benchmarks will be guesswork.
