EA has cancelled all Titanfall pre-orders in South Africa following network testing that found in-game latency to be unsatisfactory.
On EA's South African Facebook page, the publisher said:
"After conducting recent online tests for Titanfall, we found that the performance rates in South Africa were not as high as we need to guarantee a great experience, so we have decided not to release Titanfall in South Africa at this time.
"We understand this is a disappointment for local fans and will keep fans posted on any future plans regarding the release of Titanfall in South Africa."
In February, Microsoft responded to South African concerns over possible latency.
The company said it was "currently providing Azure services for South African customers through a vast worldwide network of Microsoft Datacentres. This allows us to provide world class service levels and deliver on financially backed Service Level Agreements. This worldwide network of Datacentres currently does not include a South African deployment due to the high Service Levels currently being experienced by our South African customers."
Titanfall is coming to Xbox One and PC on March 14.
The Xbox 360 version is being developed by Bluepoint Games and will be released on March 28.
