May 9, 20251 yr Hello All, Currently building my dream system. Using all my M2. slots will reduce my PCIe 5.0 slot from x16 to x8. Can anybody tell me how much of a performance hit my ASUS 5080 will take when using MSFS2020 and MSFS2024 in 4K? CPU is the Ryzen 9 9950X3D. Regards, Steve.
May 9, 20251 yr It's quite minimal, if any. However, you may consider getting 2 larger SSDs (4TB) that will give you a total of 8GB NVMe storage, without comprising PCIe bandwidth. One to CPU directly, one via the chipset. Zicheng Cai
May 9, 20251 yr Yeah I would just leave the x16 alone if i were you. Let the PCIe Lane to run at its full potential. You have a good card, don't let a NVME drive gets in the way

You have a good card, don't let a NVME drive gets in the way PCIe 5 8x is the same as PCIe 4 16x. No one will notice the difference.

May 9, 20251 yr Author Thank you all for the replies. Luke, will a high end card like an ASUS RTX 5080 not make much use of the extra bandwidth of the x16. Steve.
May 14, 20251 yr Commercial Member Not really. The PCIe bandwidth is just for loading textures into VRAM. Cheers Luke Kolin I make simFDR, the most advanced flight data recorder for FSX, Prepar3D and X-Plane.
