Homefront: The Revolution developer Deep Silver Dambuster Studios has acknowledged the performance present in the game today - its day of launch.
Writing in a post on the game's official forum, community manager Craig Turner admitted the game was not yet at its best.
"We're aware that performance - particularly frame rate - is not currently where we want it to be, and we are working on additional patches to help address these issues and more," Turner explained.
"Patch notes per platform will be available on the community forums and on Steam when they go live."
The post comes a day after Digital Foundry's performance analysis of the game found it fell short of its console graphical goals.
"Homefront: The Revolution is a fine game, with some superb tech behind it, but it's seriously let down by its console performance level," Tom Morgan wrote. "If you're interested in giving it a go, early tests suggest that PC is the way to go."
Homefront: The Revolution has been in development for years - during which time it has changed publishers, developers and game engines.
The finished game acknowledges its own troubled development in a post-credits message to players, thanking fans and staff both past and present.
