Since the release of the first episode last month, players have been complaining about performance issues with the PlayStation 4 version of Resident Evil: Revelations 2. A recent update improves the PS4 game's frame rate, though it reportedly still suffers from some issues.

Digital Foundry examined how the patched version of Revelations 2 on PS4 compares with both the Xbox One and unpatched PS4 versions. It's a notable improvement, estimated to be anywhere from 10-15 percent better than the unpatched version.

However, while cinematics and certain segments run more smoothly on PS4 following the patch than on Xbox One, it's the Xbox One version that manages to usually stay closer to 60 frames per second. Digital Foundry's analysis found the lowest frame rate on PS4 following the patch was 31fps, compared with 27 in the unpatched PS4 version and 44 on Xbox One.

"Overall though, there's still the sense that Resident Evil Revelations 2 is one of the more poorly optimized titles based on the mature MT Framework engine," the report states. It notes that their high-end PC was unable to run the game at 60fps at a 1440p resolution, whereas older, better-looking MT Framework games like Resident Evil 5 and 6 could run at that frame rate even at 4K.

Revelations 2's final episode was released earlier this week alongside the full retail version. There's no word on whether Capcom has any further patches planned that will impact performance, but we do know that online support for Raid mode will be coming in a free update on March 31.
