Looking forward to hearing how you get on? I'm planning an upgrade when the 3000 series ryzen come out
Finally got round to this:
Methodology - Running off a SSD. Late game where I have visibility of the whole map, ended turn and hit FFW to speed up the turn. Everything was perfectly smooth for the second or two until until I hit FFW.
CPU usage: limited to a single core being pinned, while the rest sit around doing nowt. No noticeable change in performance to my overclocked 3770k. I didn't bother showing all 16 threads because it tells the same story.
FPS/Frametimes/GPU usage tells the same story. CPU thread 7 is the one holding us up as all the AI runs through that one core, and the frametimes and GPU usage tell a tale of CPU bottleneck.
In theory, if the rumours are true, Ryzen 3000 will offer better single threaded performance so you'd see an improvement, but mostly this game just wants IPC/clockspeed so all those extra cores go to waste. Different story entirely on BF5, so horses for courses and all that.
