With just one week to go before The Witcher 3: Wild Hunt arrives, Polish developer CD Projekt Red continues to improve the game’s technical performance across all platforms.

“This is the last stretch and we’re pushing hard,” CD Projekt Red CEO and co-founder Marcin Iwinski said in a statement.

“Over the last two weeks, we’ve increased performance on all platforms and started working full speed on the expansions, Hearts of Stone & Blood and Wine.”

It’s unclear what specific technical improvements CD Projekt Red has been able to make. We’ve followed up with the developer, asking for more details.

The Witcher 3 runs at 1080p/30fps on PlayStation 4 and 900p/30fps on Xbox One. The PC edition, meanwhile, may end up looking the best overall, if you have a capable enough rig to run it.

In addition to a smorgasbord of free DLC, CD Projekt Red will release paid expansions for the game in the form of Hearts of Stone (October 2015) and Blood and Wine (Q1 2016). Together, they should add around 30 hours of gameplay to an already massive game. You can buy them both together for $25.

After multiple delays, The Witcher 3 release date is May 19 for Xbox One, PlayStation 4, and PC. The game recently eclipsed 1 million pre-orders.
