CPU Ugrade?

Probably not but I wouldn't worry too much about it. Whilst I can't find anything specifically about different racing sims, this article compares gaming with the different PCI Express versions: https://www.guru3d.com/articles-pages/pci-express-scaling-game-performance-analysis-review,1.html. Their conclusion is that there's very little difference in real-world performance between Gen 2.0 and Gen 3.0 slots. The article is a few years old but I can't find anything more recent.
Thanks! :)
That what I came down to when I searched for it a few years ago! With rF2 being my main sim at the moment, it sparked my interest again. Damn isi engine :roflmao:

That is generally true, with pretty much one exception - rFactor 2. This sim has incredibly high PCIe bus usage (it's not hard to get to like 70+ percent of bus usage with rF2 on PCIe 2.0, while pretty much any other game keeps below 10 %) and apparently benefits quite a lot from PCIe 3.0.

I would certainly be interested in someone explaining why the PCIe bus usage is so ridiculously high with rF2.

But 70% usage is still not swamping the bus so should not be limiting performance - you've still got 30% overhead to play with. Logically, you shouldn't see a performance hit until the bus usage reaches 100%. Other games are just under-utilising the bus.
 
And yet people apparently see significant performance gains in rF2 by switching to PCIe 3.0. One might suggest things are not as simple as "you shouldn't see a performance hit until the bus usage reaches 100 %". Because, let's face it, in real life scenarios, things rarely are this simple, and technologies don't always behave strictly "logically".

I can certainly attest to that fact on RF2 with PCIe 3.0.
The result is night and day with it not running versus running.
I've never seen anything like it.
