Batman: Arkham Knight is never going to make use of your dual GPU set up. Sorry.
The PC version of Batman: Arkham Knight is working – mostly – but the various teams working on it have decided not to continue pursuing SLI and Crossfire support, meaning many players can’t get the most our of their hardware.
“We’ve been working with our development and graphics driver partners over the last few months to investigate utilizing multi-GPU support within Batman: Arkham Knight,” a team member identified as wb.elder.pliny wrote in response to a Steam Community query.
“The result was that even the best case estimates for performance improvements turned out to be relatively small given the high risk of creating new issues for all players. As a result we’ve had to make the difficult decision to stop work on further multi-GPU support.”
The representative said Warner Bros. is “disappointed” that it wasn’t practical to offer support for multi8-GPU usage, and apologised to “those who have been waiting for this feature”.
As absolutely everyone must be aware by now, the PC port of Batman: Arkham Knight had a disastrous launch and was pulled from sale for months. It’s back now, but it’s never going to be a very jolly experience for some players, and Warner Bros. is still offering refunds to those who are disappointed by how the game runs on their rigs.
On the bright side, Warner Bros. is looking to change how it handles port development and release as a result of this mess, apparently.
