Will MP performance be improved when upgrading a CPU bound PC?

[darkman222]

I have a CPU bound PC. I play in vR which makes it even worse to play when frame rates drop. I can fly around solo with no other aircraft with nice smooth frame rates. As soon as I fly a mission with some enemy aircraft, frame rates drops and the playback stutters. For example the 8v8 mission for the Hornet kills my CPU. Same happens for me in MP, as soon as servers fill up with other people.

So I am sure if I upgrade mp CPU I will see improvements in single player.

But my question is, will I see improvements in MP too? Or is it a lot more diffcult in that case? Maybe my CPU has to wait until all the information about other aircraft has been gathered, until it can calculate the frame, which is sent to my GPU? Are the MP stutters of same nature as singleplayer "heavy mission" stutters? Or is more involved and a CPU upgrade would not help in my case.

I believe you should try to upgrade everything as much as possible. The CPU makes a difference, but system memory and graphics card memory (even the type of graphics card and what drivers it uses) make a big impact. I have Ryzen 5 3600XT and 8GB graphics card (upgrading to 32GB soon) and 64GB RAM (upgrading to 256GB soon). The fact that I am upgrading my system that is already far in excess of the recommended requirements should give you some indication, and note that I am upgrading the graphics card and system memory first before considering a change to the CPU. Most of the time I get good performance, but if some other part of the system does something outside the game, I will see a quick stutter (very rarely).

 

If you're getting lag in single player mode then you need to fix that first. Otherwise you can't expect a decent experience in multiplayer, and you can expect to see even more problems. It's not because your CPU is gathering more information about the aircraft in the game, but because your system is dedicating some of its performance to communications with the game server, and also if you're in MP you are likely to be using other software like TeamSpeak or Mumble, and that will also be using some system resources.

Would be a lot easier to give you tips and assistance if you could post your PC specs: CPU, RAM, Graphics Card, Storage disk etc. etc.

Ryzen 5 3600X @ 4,2 gHz , 16GB (2x 8192MB) Corsair Vengeance LPX LP DDR4-3200 DIMM CL16-18-18-36 Dual Kit, Pimax 5k plus, and a brand new RTX 3090.

I tried the 8v8 mission for the Hornet. I use it since I play DCS for performance testing. If I set the Pimax to a resolution of 3860x2380 I see in fpsVR the CPU is bottlenecking with slow frame times. If I try to decrease the resolution to 2600*1604, same result. CPU is the bottleneck for single player.

 

But then I just did a test on a MP server. I tried the same with different results. in 3860x2380 I get stutters. I changed resolution to 2600*1604 and reconnected again to the same server quickly. CPU seemed fine, and no stutters. For some reason resolution seems to matter for MP performance but for single player it does not change anything.
