Star Citizen’s 4.9 patch delivers a significant performance boost, especially in demanding city areas like Lorville, with the Vulkan API outperforming DX11 for the first time and 32 GB of RAM strongly recommended for smoother gameplay. While improvements benefit a range of hardware including mid-tier systems, very old CPUs still struggle, but overall the update marks a positive step toward resolving long-standing performance issues.
Star Citizen’s 4.9 patch has brought a notable performance improvement, particularly in Lorville, marking one of the biggest boosts seen in a long time. Testing across various systems—including high-end setups like the 9800 X3D and 5800 X3D, as well as minimum spec rigs—showed that performance had been poor since patch 4.5 but has now rebounded to levels similar to those between patches 4.1 and 4.5. While not the best performance ever, the improvement is significant and more acceptable for players, especially in the city environment that had been notoriously demanding.
A key highlight of this patch is the Vulkan graphics API outperforming the older DX11 for the first time. Historically, Vulkan provided smoother gameplay with better 1% low FPS and fewer stutters but did not improve average FPS compared to DX11. However, in 4.9, Vulkan achieved an average of 81 FPS versus DX11’s 73 FPS, indicating a meaningful optimization. Although CIG has not detailed the changes behind this boost, it might be related to work done on their other project, Squadron 42. Vulkan’s improved performance is a positive sign for the future as CIG plans to phase out DX11 entirely.
RAM capacity remains a critical factor for smooth gameplay. Testing showed that 32 GB of RAM significantly improves both average and 1% low FPS compared to 16 GB, which often leads to frequent hard faults and stuttering due to paging to disk. While 16 GB is just about playable, the upgrade to 32 GB is highly recommended for a much smoother experience. This aligns with long-standing advice in the Star Citizen community that 32 GB should be considered the minimum for optimal performance, especially in demanding city environments.
CPU testing on older and minimum spec systems revealed mixed results. The AMD 5800 X3D saw a strong performance increase from 42 FPS in 4.8.1 to 51 FPS in 4.9, confirming that the improvements are consistent across different hardware. Meanwhile, a minimum spec Intel 10400 system approached an average of 30 FPS in Lorville for the first time, which is encouraging for players with lower-end rigs. However, very old systems like Haswell CPUs remain largely unplayable in cities, delivering only around 16 FPS with poor frame stability, though they may be borderline acceptable outside urban areas.
Overall, while Star Citizen 4.9 does not fix all issues, it represents a meaningful step forward in performance, especially in the challenging city environments. The improvements may be due to reduced entity counts or background optimization work, possibly influenced by Squadron 42 development. Players are encouraged to try Vulkan if possible and consider upgrading RAM to 32 GB for a better experience. The patch offers hope that CIG is starting to address long-standing performance problems, and community feedback will be important to gauge how widespread these gains are.
