Volition has acknowledged technical issues pertaining to the PC version of Saints Row: The Third, with a fix being worked on.
The issues are related to AMD and ATi graphics cards, and the developer has stated that although minor performance increases have been carried out, a patch won't come into fruition until they find a solution with AMD.
It’s been a few months since Saints Row: The Third hit Steam and as you know an issue has come up where certain AMD/ATi GPU’s are experiencing micro-stuttering and general performance drops on capable machines. This has mostly been seen with cards in the 5xxx or 6xxx range.
Our team has provided multiple patches and updates attempting to correct this issue by adjusting key parts of Saints Row: The Third at the guidance of AMD/ATi, and they have shown mild improvement. Those with SLI no longer see micro-stuttering, and based on our performance tests, we’ve been able to increase overall performance. For those with affected cards, we’re still not up the level of quality we all expect from a Volition game, and we thank you for your patience as we work with AMD for a solution. As soon as we have more updates regarding this issue, we’ll be sure to let you know.
Saints Row: The Third launched back in November last year, with the third installment going on to ship more than four million units.
