BFV is a really CPU-intensive game.

@VegetableStu
Yeah. Well, I did have some usual stuff like Steam, Spotify, Anti-virus etc. running in the background but nothing major that would take up significant CPU resources...

I suppose the era of quad-cores for high-end gaming is over, considering a 1080Ti isn't the most powerful GPU on the market and I wasn't playing at a ridiculous resolution compared to hardware, 1440p is more than appropriate for that

I expected more from the most high-end mainstream CPU less than 3 years ago

The 1080 Ti is still the second most powerful gaming GPU there is when you factor only the RTX 2080 Ti truly outpaces it as the 1080 Ti is a tad faster than the Radeon 7 and trade blows with the 2080 so I wouldn't call accurate your sentence there

You're lacking the cores is all, with these games fully utilizing 4 cores (with or without HT) you really have no breathing room for anything else, the i7 8700 I have keeps up pace perfectly fine which leads me to believe it that isn't that games are using more cores but rather that they finally can extract all quadcores has to offer to the point you have no more room for OS and side/background stuff.

Also rocking a 6700k + GTX1080Ti with a 1440p 144hz monitor.
Haven't played Battlefield V since the open Beta, but I found GPU and CPU were both pushed to their limits. From memory I could still get over 100FPS pretty consistently playing at 1440p High. Obviously the CPU was pretty well pegged so dropping the graphics detail down didn't really help.

Gaming with my 6700k is for the most part fine. Where I really notice its age is if I do a small video edit and try to export the file and it takes a million years to complete.

@Spotty Yeah, gaming with a 6700K is for the most part more than fine, it's still a great gaming GPU however it does start to show its age... Streaming more CPU-demanding titles is also a challenge if you aim for good quality content

It's a lot better than Ryzen at running older games, MMO games and unoptimized titles but its multithreaded performance isn't that good nowadays (outpaced by a Ryzen 5 1600 in that regard)

I'll probably upgrade soon, I only wonder about the pricing - X570 boards are rumored to be both high-end and expensive (similar to most Z390 boards) and I'm yet to read into the specifics of X370 & X470 support of Zen 2 CPUs and features.

Not sure if this is a CPU problem TBH. AFAIK, BFV isn't exactly well optimized. (which is weird, cause BF1 was extremely well optimized)
