OK so there were a lot of complaints on here before release that the GPU and CPU were not being fully utilized by the game. Since release I was at first pleased to see that the game was using 99% of my GPU however my GPU temperature is getting no higher than it does at idle (30-40 degrees) and my framerate is EVEN LOWER than in the beta. THIS IS INSANE, I can therefore only assume that Arma is faking the full use of my PC's hardware and therefore impacting further on game performance.
Bohemia, if you are just going to try that old trick of faking a games utilization of hardware like this please don't because I can no longer even play this game on high let alone the ultra settings I had during the beta!
