Not necessarily. GPU intensity isn't directly connected to visual fidelity, as visual fidelity is subjective and doesn't correlate with what is being rendered or calculated in game.
GPU intensity *is* connected to the number of objects that have to be rendered and therefore the viewing field and distance. As such, any recent first- or third- person game is likely to be more demanding that one employing a top-down perspective.
The only thing you can do is update drivers and the usual, the game itself doesn't have any performance issues. Having high requirements to run well doesn't fall under a 'performance issue'.
Waiting for D:OS updates is another option. The current build still has debugging code (look at the logs it generates in the game folder) which future updates may remove. Also performance optimisation is usually the last step in game development so D:OS may well show significant improvements in later versions.
Checking GPU utilisation and GPU memory usage using a utility like
MSI Afterburner may be worth doing though - using more video memory than the GPU has (1GB for a
"standard" 560 GTX Ti) will result in serious performance drops. In that case, lowering graphics settings (texture quality particularly) would be worth doing.
