2) 60fps+1080p video preview [123mb]

===================================================

Note:
-This particular mod CAN be used while GFWL is active
- This mod does not make everything run at twice the speed, you simply view 60 frames in one second as opposed to 30 frames in that same second. Gameplay is the same, it simply runs smoother.
- You will need a recent CPU and Graphics Card to do the 60fps mod justice. If you do not have a semi-powerful system then installing this may make the game run poorly in active areas (see: blighttown). If you experience slow-downs between 15 and 30fps, the mod is working but you may need to reduce the resolution through DSfix, or uninstall the mod.
-If you experience framerate drops below 30 because of the mod, then make sure you have texture overrides/dumping disabled and try to reduce resolution through DSfix. If this doesn't work, then this current version of the mod is not recommended.

TIP: ctrl+F \"60fps\" to find what you\'re looking for.

I speak for everyone when i give my thanks to From Software for Dark Souls, Namco Bandai for the port, Durante for DSfix and \"NWKS\" for the 60fps mod.
