The above three images represent the High/Med/Low presets. Medium and High both look pretty similar and the world of New Bordeaux looks quite nice, but even the Low preset looks good—it wouldn't surprise me to find out the "Low" setting is basically what you get on a current-gen console. Gangster Games Online, Lighting and reflections are clearly different, but I wouldn't say low quality looks bad—I might even argue that without the heavier antialiasing and other effects, the sharpness of the low preset is actually preferable to the other settings. But the water quality is definitely worse, so maybe reflections is one to turn back up if you have spare performance.

In terms of performance, I didn't conduct extensive testing with Mafia City, but I did run tests using the three global presets, and I did a bit of checking on which of the individual settings have the largest impact on performance. What it comes down to is that there are two major settings that can tank performance: reflection quality and volumetric effects. Three other settings—ambient occlusion, shadow quality, and antialiasing—can have a moderate (maybe 5-10 percent) influence on framerates, depending on your hardware.

So how does the game run? Not so great. I can confirm that the game will struggle to hit 60 fps even on high-end hardware, at least if you want to run at the high preset. My test sequence consists of running around the city a bit, climbing into a car, and then driving along a set path. Indoor areas aren't as demanding, but a large portion of the game is spent in the city, and that's where players are most likely to encounter choppiness.
