Below is a video demonstrating a graphical fix created by Durante, a fan of Dark Souls with a programming background who has removed the lock on the internal resolution and play the game in full 1080p. It’s a downloadable mod titled “DSfix02″ for the PC version of Dark Souls.
From Durante’s blog:
I managed to fix the issue with the cut-off text and button prompts. It’s a rather brute-force fix, so please test and see if it introduces any new issues. This version should also fix downsampling for everyone and may improve texture clarity (forces 16xAF on everything).
From Durante’s post on the NeoGAF forums:
What is it?
It’s an interception d3d9.dll that you place in the same folder as the game executable. It intercepts the game’s calls to the DirectX 9 API and changes them as necessary to enable a higher internal rendering resolution.
How do I use it?
Place d3d9.dll and DSfix.ini into the game’s binary directory. (The place where DARKSOULS.exe is)
You can open DSfix.ini with a text editor to adjust the desired internal resolution.
Will it work?
So far, this has only been tested on my computer, on the first half hour or so of the game. I can not and will not guarantee that it will work for anyone else, or not have any adverse effect on your game/computer. Use at your own risk! If you encounter any issues that seem like they could be caused by DSfix, let me know.
Why is it still blurry?
I don’t know at this point in time. It’s already clear that there is a lot more detail and less aliasing using an increased framebuffer resolution — as you would expect! — but there is some residual blur. I’m trying to work out if this is due to my method or something inherent in the game. I will certainly continue working on this.
Will it cause performance problems?
That depends on your system configuration. Usually, performance scales rather linearly with framebuffer size, and so far this game does not seem different. My 660 maintained a locked 30 FPS throughout ~ 1/2 hour of testing in the starting area of the game at 2560×1440.
Can I donate?
If you really want to donate I won’t say no, I’m not particularly rich :P.
Durante has also provided a donation link for Dark Souls players willing to donate for the fix.
