# Top runs: * **Highest FPS**: `sc_7800xt_lorville`. This run had the highest average FPS, outperforming all others by a significant margin. * **Smoothest FPS**: `sc_5700xt_a18`. This run had the lowest standard deviation in FPS, indicating the most stable performance among the runs. * **Best overall**: `sc_7800xt_a18`. This run strikes an excellent balance with high FPS and low variability, ensuring both high performance and stability. # Issues: * The runs on the AMD Radeon RX 5700 XT demonstrate noticeably lower FPS and higher frame time variability compared to the AMD Radeon RX 7800 XT, likely due to GPU differences. Despite similar system configurations, the hardware disparity significantly impacts performance. # Summary This benchmark compared Star Citizen performance focusing on VRAM usage and spillover to RAM, utilizing two different GPUs (AMD Radeon RX 5700 XT and AMD Radeon RX 7800 XT) on similar system configurations. The AMD Radeon RX 7800 XT consistently outperformed the AMD Radeon RX 5700 XT in terms of average FPS and stability, highlighting the significant impact of newer and more capable hardware in gaming performance. The testing conditions, including the Linux OS and specific kernel settings, remained consistent across runs, ensuring a fair comparison centered primarily on the GPU capabilities.
