The PC version of Batman: Arkham Knight was released in rough shape, and the complaints have been rolling in. While the game is being fixed, Rocksteady Studios has released a guide to getting good frame rates in the game.
Their advice? Sacrifice just about every graphical bell and/or whistle at the low end.
Minimum Hardware Specs or equivalent
- Resolution: 1280x720
- V-Sync: Off
- Anti-Aliasing: Off
- Texture Resolution: Low
- Shadow Quality: Low
- Level of Detail: Low
- Interactive Smoke/Fog: Off
- Interactive Paper Debris: Off
- Enhanced Rain: Off
- Enhanced Light Shafts: Off
This should give you an expected, capped 30 frames per second. They do not yet have recommended settings for the Ultra specs. The post also warns against some of the work being done in the community to "fix" the game, and suggests using an SSD if you have access to one.
"We do not recommend that users change anything in the game’s .ini files as this will potentially negatively impact performance, including frame rate, and stability," the post states. "At this time we do not recommend using NVIDIA’s GeForce Experience or AMD’s Gaming Evolved Optimization tools."
Why would you want to actually use the tools available to you as a PC gamer anyway?
In case you want to go a bit deeper and ignore that device, this is a great thread on how to adjust the .ini file to increase your in-game performance, or remove that 30 frames per second cap.
Most of these tweaks are easy to do, especially if you have experience manually adjusting your games settings via these text files, but there is always the possibility you could break something so proceed with caution.
Some of these adjustments are also aimed at making the game look better rather than run better, so make sure you have a clear set of goals in your head before you start moving things around.
