Unparking cpu cores

[Bee_Sting]

Unparking cpu cores will it get you better performance in Dcs World?

No. DCS is single threaded.

 

I suspect in DCS 2.0, the answer will be no as well, even though it will be multi threaded.

 

Core parking is a power saving feature, and running anything as intensive as a game is sure to make the system run at full power and unpark all cores automatically.

 

It is extremely unlikely that manual control over core parking would do much good. That said I will not rule out there being some combination of hardware or legacy software that doesn't take kindly to core parking, and in those very specific situations, disabling it could help. I would need benchmark backed evidence of such a thing to believe it though. I've seen too many fools online to trust anecdotes.

From what has been stated 2.0 will only have two threads on the processor just like the current engine. Sli/crossfire is stated to have better support with new engine. So brute power or high overclock on processor is more important than having a 4 core or 8 core processor with current dcs world and from what it looks like will be the same in dcs 2.0

Really? My mistake. I guess there isn't enough that can be parallelized to make it worth the work.

 

My point about CPU parking still stands though, and extends to other games / software.

BF3 and BF4 you can get 15 to 20 percent increase in performance,but in some applications they will crash when cpu cores are unparked.

Disable C1E abd C6 Power States in the BIOS and cores will not park or throttle down.

 

Has nothing to do with windows or applications.

From my sig (below), you can see that I have two GFX cards in SLI. My CPU is overclocked and very stable. Yet, in many cases such as online at Sochi with lots of activity, my FPS gets down into the low 20s and, occasionally, in the low single digits. Away from the hustle and bustle, my FPS goes up to the high 60s or more.

 

From what I can tell, much of the work that needs doing does not involve graphics rendering but code processing such as trajectories, object collisions, and the like. From what I have heard about nVidia's CUDA, my graphics cards can do wonders to help out the seriously overworked CPU cores. And, from what I have heard, DCS currently operates on just a single core. Am I to understand that 2.0 will still be using one core?

 

Is there any way I can improve my Sochi FPS without lowering my features such as water and heat blur?

 

If DCS is currently giving me 20 FPS around a busy Sochi, what FPS can I expect out of 2.0 around the same busy Sochi?

good advice, but doing that to an Intel reference Z77 chipset board will cause non boot... such a finicky chipset it is

 

 

best to disable the function in the registry, taking great care to get it right (that way, if the throttling is required it is still there, but the processor will always have all cores functioning instead of just acting as one expanding CPU)

research, read, re-read, backup, and then do it.. as a general advice for any who would consider the option

 

 

and it does make a difference

I would really honestly love to see proof of this. Because I've never seen benchmarks proving this, and I'd love to see them. (no snark or sarcasm!)

 

I've only seen unscientific anecdotes that I really cannot trust.

Having all cores operating full power for gaming works as when cores spool down, idle or park (turn off) it causes issues when a thread is moved from on core to another or when one thread of another application is running on a throttled core etc.

 

I disabled all the power saving features in my bios fine, if I know Im leaving my Pc for a few hours I hit a hotkey that downclocks the CPU via AMDs software, when I come back stock clocks can be restored easily, as well as my 5.15GHz overclock profile.
