Quantifying Memory Bandwidth Bottlenecks in MS Flight Simulator 2024
Checking benchmark report #BW-2026-09 on Corsair Vengeance RGB DDR5 6400MHz with Win11 24H2, the bandwidth situation was critical. 3DMark stress tests showed that during heavy terrain loads, the memory throughput was peaking at a glitchy 98% of total capacity, leaving only 2.1GB - 2.6GB of usable headroom. It was a total disaster. I had to kill every unnecessary background process and scrub the Windows Search index via the services panel to carve out some room. By pairing this with the in-game performance overlay, the frame rate oscillations finally tightened into a rock steady 55-60fps range, with a variance of only 3% compared to the reference labs. It's mostly smooth, but let's be real: in hyper-dense city environments, the L3 cache hit rate takes a dive. You'll still see a couple of sharp frame drops regardless of how much bandwidth you throw at it. It's a systemic limitation of how the simulator handles dense geometry that no RAM tweak can fully bypass.
