GPU or CPU?

Thanks, but that thread just discusses hardware.

(Sigh) i would like to see this question answered as well . Just got some unexpected results from an Oculus debug optimisation . Funny how you can stumble across really significant info , but getting a straight answer to a simple question ?

Among graphics settings, anti-aliasing affects GPU. Trees, shadows and vis range affect CPU and GPU about equally.

My guess is the settings mostly work on your GPU, while the battlefield (amount of units, how many AI, how many instructions, etc) works on your CPU (& RAM), this is basically just calculating (CPU) while the former is rendering (GPU).

 

At least, that's what my own logic tells me. ;)

before the GPU can draw the pixels, the CPU has to calculate the geometry and send that data to the GPU.

 

this is why complex or high detail scenes require so much CPU.

The modules use DLLs developed by the module maker. They can do everything in there.

Yeah, but while it's good to spread out the load it might not matter much to us when we choose CPU. Because there might be 30 threads but 60 % of the work could still be done on one of those threads. In that particular case a 2 core CPU would be enough because the performance on that main thread is what's critical. The other core can easily keep up even if it runs all the 29 other threads and some background processes all by itself.

 

Long story short, good single thread performance is still more important than getting a CPU with lots of cores.

Hopefully one day..... it will be mostly GPU.

 

Any half decent CPU will do the job well.

 

Not that bad after all

 

Well after some more testing and UNCHECKING my Vsync I can say this:

My FPS are in the 50's (X4 MSAA , X4 aniso, all setting on HIGH, VIS range ultra no CIV traffic)

on extremely dense areas or lots of air trafiic going on they can drop to high 20's

Only thing still present are the occasional BLACK FLICKERS here and there which I don't know where they come from or what are they all about.

I would check to see what difference you see when changing graphics to high instead of ultra.

Shadows are the biggest hit - try lowering them.

For best performance your System drive should be a SSD NVM M.2 (even with 32 gb RAM DCS, or probably the Windows system, still writes to continuously to the page file.)

Your DCS Drive should be an SSD as DCS writes (only a small amount) to this drive - and turn off the track file)

And finally, make sure DCS is running on more than one core - since the second last Beta update mine now randomly starts with either 1 or all selected.

In VR - which requires more grunt than normal, I get a steady 30 to 45 FPS with no stutters and no flickers on busy MP servers on all maps in all areas - and my pc is nearly 3 years old!

 

One big but - for VR I’ve found the sweet spot for my CPU is 4ghz. Lower than this and even with all the above my frame rates are halved.

About 7 pages back silentbob, I advised a gpu rather than a cpu, so after 16 pages of good and bad advice I can set you straight. I was told a GPU upgrade with my 7+ year old 3770K, I would not notice any difference.

Overclocked GTX 970, everything on low, no eye candy, PD of 1.2, 2xAA I was getting 22 FPS.

 

 

Stock 2080 everything on high, PD of 1.5, 16xAA, 4xMSAA 2xSSAA, visib range ultra, I am getting 45 FPS.

 

 

So to answer you opening question, a GPU

I agree, same here. With i9 9900k and my old 1080 (with Rift S) around 20s, when I put the same system with the 2080ti the story totally changed. So yes, GPU. (or both) :thumbup:
