Experiencing significant CPU bottlenecks in Skyrim with a 7900GRE and 5600x setup is common when running extensive mod lists, particularly those featuring high-resolution textures and multiple city overhauls. Frame rates often drop sharply in urban areas, likely due to excessive draw calls overwhelming the processor. A potential solution was discovered through a community thread that offers .ini tweaks to mitigate this performance limitation.
After applying the recommended adjustments via BethINI, the most notable improvements came from modifying specific LOD fade settings: setting fLODFadeOutMultObjects to 6.0000 yielded a 13% increase in GPU usage, fLODFadeOutMultActors at 5.0000 provided a 5% boost, and fLODFadeOutMultItems at 3.0000 added a 3% improvement. These changes delivered a clear uplift in frame rates without any immediately noticeable visual degradation, offering a practical way to reclaim performance in demanding modded environments.
