Cyberpunk 2077 dev warns PC players to test their cooling systems before Phantom Liberty arrives

A lead developer working on Cyberpunk 2077 has warned PC players to test their cooling systems before the game’s big update arrives later this month.

The long-awaited Phantom Liberty expansion will be released on September 26, along with a major Version 2.0 update which will entirely overhaul the way the base game is played, according to CD Projekt Red.

However, the game’s lead scene programmer Filip Pierściński has taken to Twitter to warn players that the expansion may place extra strain on some PC setups, particularly when it comes to CPU workload.

“Before [we] release Cyberpunk 2077 2.0 and Phantom Liberty please check conditions of your cooling systems in PC,” Pierściński tweeted.

“We all use what you have, so workload on CPU 90% on 8 core is expected. To save your time please run Cinebench or similar and check stability of your systems.”

Cinebench is a free program that tests a PC’s hardware capabilities. By running it in advance, players will be able to determine how well their PC will cope with Version 2.0 of the game.

CD Projekt said last month that its decision to only release a single expansion for Cyberpunk 2077 was a technological one due to the company’s switch to Unreal Engine development.

Alongside the news that it was working on the next mainline Witcher game, the company announced in March 2022 that it had entered into a 15-year partnership with Epic that would see the companies collaborate on Unreal Engine projects including engine and game development.
