I often visit Game-Debate for latest game news and articles. I came across Mafia 4, this game is yet to come and not much about it's requirement are known.
They provide a couple of "predicted system requirements". So, I ran a compatibility check for the game.
I was shocked after the result I got, I got a Grey Tick on my GPU (Radeon HD 7770 Sapphire Edition). Though the GD rating of my GPU was '8'. I can play 30+ FPS at any resolution possible.
Grey-Tick: Low-to-Medium settings.
Green-Tick: Medium-to-High settings.
Gold-Tick: High settings.
I played Crisis 3 on Ultra settings with this card, I ran a compatibility check for BF3, Sprinter Cell- Blacklist, Hitman- Absolution, Assassins Creed- Black Flag, Elder Scrolls- Skyrim, etc. and got a Gold-Tick for all of them.
I ran a compatibility check on GTA-V, BF4, etc and got a Green-Tick.
Playing at ultra might be too much but I could really use a Green-Tick.
Is this game too much, I mean uses more GFX than GTA-V or GTA-Online?
If you can play Crysis 3 on ultra you must be using a very low resolution which game debate likely does not take into account. If you posted a thread saying what settings can I play Crysis 3 with a Radeon 7770 you would get answers of low and medium. If you look at this benchmark they didn't even bother testing the 7770 on very high because the 7850 only got 22FPs @ 1680 x 1050 which is not considered by most as playable.
Just checked game debate and they say the 7750 is the minimum just to play Crysis 3 and you are only 1 card above that. Any way according to them Mafia 4 is much less demanding than a game you play on Ultra.
