PCI latency has no impact on rendering, but your card/motherboard may fallback to PCIE3 instead of using PCIE4, in which case filling the cards entire VRAM from RAM could take an extra half-second (slowing the loading of new textures an infinitesimal amount).
- mtsr 4y agoModern engines also do a lot of streaming data to VRAM, rather than loading everything up front. So it’s not necessarily a single delay and could very well impact framerates etc.
- eropple 4y agoIs there anything out now, or even on horizon, that's materially impacted at running at PCIe 3.0 rather than PCIe 4.0 rates? I can't think of much.
