The PC port for Batman: Arkham Knight was troubled enough already, and one of the slim solutions players might have had to guarantee some stability and decent performance has just been shot down.
In a post on the Steam forums, one of the developers has confirmed that all work on implementing multi-GPU support for the maligned port has been abandoned indefinitely due to the poor returns it would have garnered.
"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," one developer posted in response to multiple questions about Crossfire/SLI support. "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. We are disappointed that this was not practical and apologize to those who have been waiting for this feature."
The confirmation that multi-GPU support will never arrive adds to the already long list of disappointments for Batman: Arkham Knight's PC release. The game's performance was so atrocious on launch that it was pulled from sale for a few months. Mortal Kombat X's PC launch was also troubled, with users finding they had to redownload the game's entire game each time it patched among other problems.
