Yes
The big issue really is connection speed, specifically contention ratio. Some VPS providers oversell so they may have many many servers running on 1 connection, leading to bad lag.
The same applies to all resources. It could be that 20 other VPS are also running game servers on that same Xeon, which would cause slow response times.
The only way you can really test is to try it. I'd recommend you go with a VPS service that offers a month free trial or a money back guarantee, then you can setup, and if the lag is too bad, change to another provider.
