Except for DOTA2. At peak hour (as report and tested with friend) the in game latency will spike to over 100 ms. I directed DOTA2 traffic to use a Singapore VPN and when friend reporting issue over 100 ms, I check mine that were on VPN still at 21 ms. We both using UniFi biz 100Mbps.

VPN are some time useful but not all the case. You result maybe vary.

Best regard.
