Xbox One bagudkompatibilitet

For mig er det bedste selling point efterhånden at hvis jeg vil spille et X360-spil, så behøver jeg stort set aldrig finde min x360 frem.

"We designed the Series S to enhance the Xbox One S games in a way that the Xbox One X can't do," system architect Andrew Goossen tells us. "We made it easy for existing Xbox One S games to be updated to run with double the frame-rate when played on Series S as well. When games are updated, existing games can query to determine whether they're running on the new console. And in terms of the performance, the Series S provides well over double the effective CPU and GPU performance over the Xbox One, making it pretty straightforward for the games to do this. And in fact, the Series S GPU runs the Xbox One S games with better performance than the Xbox One X."

The way Xbox One X handled non-enhanced Xbox One S titles was interesting - effectively users saw the enhanced GPU only running at half-rate, its compute units split between vertex and pixel processing. The new consoles are designed to run legacy Xbox One titles with the full power of both CPU and the new RDNA 2 GPUs.

"There's no real perf tuning necessary when you do this, and so often it's just as easy as changing three lines of code, and then the game works." Goossen adds. "Even when it's not that easy, the fixes are still pretty minor. We had one triple-A title where doubling the frame-rate really worked perfectly, except that the crowd animation was twice as fast as normal. And so, those sorts of fixes are typically very, very easy for developers to go fix. We're working with game developers and publishers to update [their titles]. It'll basically be select games that run at a doubled frame-rate on the Series S."

Some games will be able to see this functionality enabled by the developer themselves, while others may be collaborations between the game maker and Microsoft's compatibility team.

"In some cases, for more service-based games or games that are still have active communities, it'll actually be easier for the developer to do it," says Xbox director of program management, Jason Ronald. "And then in other cases, we may be able to do things at our level, on behalf of the title, similar to how we've done it in the past. These are all things that we're actively working through as we get closer to launch and we'll have more to share about specific enhancements in specific titles closer to launch."

So, as we understand it, existing Xbox titles can be enhanced for both Series S and Series X in different ways - the compatibility team can step in with its own specific type of magic, opening the door to running 30fps games at 60fps and 60fps titles at 120fps.

Der kan ikke være tale om en eller anden form for motion interpolation i stedet? Kan huske at Lucas Arts eksperimenterede med den slags for år tilbage, men det kom vidst aldrig i brug.
