I have an 8086k and upgraded from a 1080ti to a 3090
The improvement has been negligible.*
The real bottleneck is CPU and I’m actually not sure that the CPU which can truly chew this game up and spit it out without breaking sweat has been made yet.
*I need to qualify this statement.
Performance when gaming “flat” (1440p monitor) is largely unchanged from the 1080ti. I probably see the DevMode FPS message “limited by GPU” a lot less with the 3090 but I still get horrific stutters and unexplained frame rate drops (and sometimes it can tank to single figures out of nowhere)
However, VR performance is massively improved. VR wasn’t really possible at all with the Valve Index in this sim but I’ve had a few flights with it now which were “ok”
(VR in IL-2 with the 3090…now then! Wow. Very smooth indeed.)
So yes. At some point a GPU upgrade will be worthwhile, especially if you run 4k or VR.
However I think the CPU, memory and drives are key to a smoother experience and that a 1080 should be able to dial in reasonable performance still. Not great, but certainly not horrific either.
Note. Nvidia seems to have shafted the 1080 with its recent driver releases. I noticed a significant enough performance loss across a few titles that I wondered if the hardware was choking. Benchmarked, rolled back the drivers, benchmarked again…indeed ver.460.x was wrecking performance.
I think rolled back to 457.x - do a web search there is actually a specific version (maybe 456?) which the 1080 really shines.
This seems normal for older GPU’s I have a “utility” PC which I threw an old gtx 770 into. That particular card needs to have a particular (and old) driver or it will occasionally black screen and do other wierd stuff.
