Report: Performance Issues in iniBuilds A350 Series Linked to Ineffective DLSS/TAA Optimization Overview The iniBuilds A350 has faced significant criticism for performance degradation in Microsoft Flight Simulator (MSFS), particularly regarding the lack of performance improvement when switching from Temporal Anti-Aliasing (TAA) to DLSS 0.4. While the aircraft initially received praise for its visual fidelity, recent updates have led to severe frame rate drops, stuttering, and inconsistent optimization across hardware configurations. This report synthesizes user feedback and developer responses to outline the core issues and potential resolutions. Key Performance Issues Ineffective DLSS/TAA Implementation Users report that enabling DLSS 0.4 (Nvidia’s AI-driven upscaling) fails to resolve performance bottlenecks, with minimal or no FPS gains compared to TAA. For example, one user noted that at busy airports like EGLL, FPS dropped from 25–30 to 14 post-update, even with a high-end RTX 4080 Super. Similar complaints highlight that DLSS adjustments do not mitigate CPU or GPU load spikes, suggesting poor integration of upscaling technologies with the aircraft’s systems. Basically, there is no difference in performance between DLSS AND TAA. Post-Update Performance Regression Multiple updates (e.g., v1.0.6 and v1.0.7) introduced severe performance regressions in MSFS 2020, including stuttering, reduced FPS during critical phases (e.g., landing), and crashes linked to WASM modules . Users with high-end hardware, such as RTX 4090 and i9-14900K systems, experienced worse performance than older add-ons like the Fenix A320, indicating unresolved optimization flaws. Inconsistent Optimization Across Simulators Performance issues are more pronounced in MSFS 2020, while MSFS 2024 users report smoother operation. This disparity suggests that iniBuilds prioritized optimizations for the newer simulator, leaving MSFS 2020 users with unaddressed bottlenecks, such as excessive node counts in cockpit models and inefficient texture streaming.
