If you’ve been playing the brilliant XCOM 2, you might have noticed there’s one aspect of the game holding the rest back: it’s technical performance. Frame rate issues, freezing and bugs in general have been impacting player enjoyment since launch, but apparently Firaxis weren’t aware of these issues before shipping.

While you’re waiting for the fixes you could play the rest of the games in our picks of the best strategy games on PC.

“I can honestly say that we didn’t know it would be this way at launch,” said lead designer Jake Solomon to RPS.“Maybe this is damning on me, but I’m sitting here talking to you now on the laptop I use to play it on, and I didn’t see these issues. We didn’t catch this stuff in compatibility testing. We’re fully, fully accountable for the product in people’s hands, so we certainly take responsibility for it.”

It seems bizarre that nobody noticed the issues during QA and compatibility testing, but here we are. Solomon says the reason the issues weren’t caught is because of how “sporadic” the issues are, affecting clusters of players but with large portions completely unaffected.

Apparently at this point it’s the first thing the team discusses when they enter work in the morning and Firaxis are “working very furiously” on bringing a fix, following the other day’s hotfix. Solomon wouldn’t commit to a timescale for a broader solution, however.

When it works, XCOM 2 is one of the finest strategy games ever made. Why not read our XCOM diaries, where seven men share one save and the fate of humanity hangs in the balance.

Thanks, RPS.
