IT is one of the most anticipated games of this year. Here we will be working on various game issues. Because it is common that the game might have some bugs due to which you are unable to play.

I am making this guide after working on various errors that I had found while playing. And most of them are easy to fix. There is a also a patch released for Assassin’s Creed Unity which commonly resolve various problems.

Before trying out the manual methods below you can start with downloading the Assassin’s Creed Unity Day 1 patch and try that. Or else this guide is open to give you maximum solution.

Start with checking the maximum and minimum system requirements to run Assassin’s Creed Unity on pc. This really matters a lot. Without checking that if you try to play there can be lot of issues. So let’s have a look on the same.

Minimum System Requirements:

• Operating System: Windows 7 SP1, Windows 8/8.1 64-bit
• CPU: Intel Core i5-2500K @ 3.3 GHz or AMD Phenom II x4
• Memory: 6 GB
• Graphics Card: NVIDIA GeForce GTX 680 or AMD Radeon HD 7970 (2 GB VRAM)
• DirectX: DirectX 10
• HDD Space: 50 GB

Recommended System Requirements:

• Operating System: Windows 7 SP1, Windows 8/8.1 64-bit

• Memory: 8 GB

It is quiet necessary to verify the system requirements. That plays a vital role in the game performance. If you are having a good high end pc then you won’t face much issue with the resolution and graphic output. And you can also optimize the settings as per your need. But if the system requirement is low the game might crash.
