No benchmarks from me. But using 2024 I have learnt:
- A very fast NVMe drive is needed for the streaming cache.
- The cache is the bottleneck loading an airport/scenery
- Fast cpu to crunch the scenery and send it to GPU. The huge L3 cache on the X3D cpus may still help with fps.
- The sim does DX12 magic. So ideally we want a gpu driver thats good with DX12.
- Loading of new airport can peak at 300 Mbps for 1 or 2 seconds on my 380 Mbps broadband.
- The flight only displays Start Flying when the final network packet is downloaded, and crunched by the CPU.
- A rolling cache writes new data over the oldest data when full; the old data is lost. (Circular buffer - Wikipedia)
- Considering all the above we want the cache as big as possible and as permanent as possible (on a PC)
- For users with ample very fast storage, a permanent cache or set of caches may improve performance.
- A PCI 4 motherboard is on my shopping list - it shuffles data around at twice PCI 3 speeds and is a good price point. (PCI 5 is more expensive and I don’t know if PCI 5 GPUs exist or if it makes a difference)
I hope that helps.
