Nascar Posted July 12, 2023 Posted July 12, 2023 I have a 9900k/2080ti and am GPU bottlenecked. I always see people recommend the highest CPU and am curious if it's actually a benefit. Are any CPU cores getting pegged when using these cards?

Hiob Posted July 12, 2023 Posted July 12, 2023 (edited) Depends very much on the particular scene and your GFX settings. You can have a 4090 be the bottleneck if you crank up all the GFX in a CPU low environment (little AI, few units, single player). And you can have it the other way round. There is no definite answer to that. In general, I'd say, you're still more likely to be GPU bottlenecked unless you have a very sub par CPU. But it can change forth and back in a single mission. Some other games lately (not DCS) have started to turn the tables though. Cyberpunk 2077 and Witcher 3 Next Gen in particular are CPU hogs. You should see it from a different perspective. Compared to the GPU load, the CPU load fluctuates a lot. When you look at your average FPS across a whole playing session - when you are not GPU bound - your asking not enough of it in terms of visual gimmicky....

Pilotasso Posted July 12, 2023 Posted July 12, 2023 (edited) Absolutely get the 7900XTX. Your CPU is fine. I have an RTX 4090 and I had to buy a new case, PSU and now changing the 12VHPWR power cable due to black screens (swapped the original with a CABLEMOD third party unit only to get a bad batch, and I had to order one from the same PSU maker tssk tssk). This card is very picky with power requirements as well as overall component quality in your system. It's pretty mighty in DCS though. Save yourself the trouble and get the 7900XTX if your main game is DCS and ray tracing is not a thing for you. Uses normal power cables, less picky with your PSU and fits in more cases. you should be getting similar performance with 400$ savings. Should be a massive upgrade from your 2080Ti. My PC specs are: 5950X CPU RTX4090 SEASONIC 1000W PSU 64GB of 3600Mhz DDR4 I run the game at 4K/240Hz I run all high settings with view distance at extreme and clouds on ultra. In multiplayer RAM / VRAM usage is around 28GB / 22 GB respectively (shocking, yes). since the 7000XTX has also 24GB of VRAM you should be able to run same settings no prob without a hint of stuttering.

TED Posted July 13, 2023 Posted July 13, 2023 I have 7900xtx and yep runs beautifully on all high settings. I’m only flying vr but rarely get over 15gb vram. No stutters and excellent fps. 2

Pilotasso Posted July 13, 2023 Posted July 13, 2023 Based in my past experience of swapping components around in my system, any CPU 4 years old or newer, 8 threads or more then the GPU will make the biggest difference. In this system I had 1700X, 2700X, 3900X And finally the 5950X. going from GTX970 to 1080 Ti was a HUGE upgrade, almost 2X uplift, each of the CPU upgrades was nice but not a game changer (around 10-20% change). Then going from the 1080Ti to this RTX4090 again, tripled the performance. Just make sure your not starved of RAM and VRAM. I would say 32GB and 16 GB respectively. 1 .
