Baldur's Gate 3 dev shows off the level of optimization achieved for the Xbox Series S port, which bodes well for future PC updates

pcgamer.com:

Little things can often matter a lot and when it comes to streamlining a game's memory usage, every gigabyte counts. One of the developers at Larian, makers of Baldur's Gate 3, has shown that the team's recent hard work has resulted in a 34% reduction in VRAM usage for the forthcoming Xbox Series S version.

The good news was shared by Swen Vincke on Twitter, via a short post with two graphs showing how the RAM and VRAM loads of the Series S port of Baldur's Gate 3 have been significantly reduced in recent weeks.

It's worth noting that out of all the platforms that Larian has developed its masterpiece for, the Xbox Series S is probably the most restrictive. This is because it only has 8GB of high-bandwidth memory, to store the game while running and use as VRAM (the remaining 2GB gets used for system functions).

The graphs start at the beginning of September, with the game using just over 5.2GB for general game RAM and around 3.5GB for VRAM. By November, though, Larian had shaved this down to 4.7GB and 2.3GB respectively. The RAM reduction is a pretty decent 10% drop but the reduction in VRAM usage is a massive 34%.

Clearly, we have no idea what Larian has specifically done to achieve this, but it's unlikely to just be a case of rendering at a lower resolution or using smaller textures. The evidence for this is that the memory testing shows only small improvements throughout September and October. If merely lowering the settings was the only thing required, then the developers would have done this much sooner.

Got a nice present from our engineers. Ensuring memory is well under control and having buffer for peaks was the main thing holding us back I think this will benefit all platforms too. Still some work left but very
