P3D V2.5 High CPU usage when loading flight

[boeingaviation 0]

Hi folks,

 

Haven't posted in a very long time.

 

Was wanting to know is it normal for my CPU usage to hit 65-75% usage on the loading of a flight?

 

I have a 4790K 4.4ghz, an EVGA GTX 970 For The Win. I used the affinity mask setting to only run p3d on 3 cores and I have been putting up with blurry ground textures.

 

I believe P3D is still very CPU intensive and I'm reading the usage of the 4 cores from Realtemp when loading into a flight.

 

Can anyone help me with some settings I should try especially to remove blurry ground textures.

 

Thanks

As far as high cpu usage when loading a flight, that is perfectly normal. Start by renaming your p3d.cfg file and letting P3D build a new one, Add only the AM. Change no other settings - that's your starting point. Unless you're flying at 500 ft an 500kts you should not get blurries. If you do, there's something wrong with your setup.

 

What add ons are you running, etc.

How do I correctly set the affinity mask? At the moment I have it set to 14. I have r core and 4 threads.

 

Is there a calculator I can use to calculate correctly so it uses the correct cores.

Try this one:

Ok thanks will have a look.

 

Is the affinity mask even needed in 2.5?

This is a good question. Best way to understand correct result, test it your self.

As I understand it at the moment P3D is only set to use Core 3 & 4 and Thread 7 with AM setting at 14.

 

I'm curious if that's why I'm seeing blurry ground textures and I also don't have Full HD monitors but that should effect the textures.

 

I will try AM mask calculator you have linked.

 

I read somewhere a while ago that P3D should use core 1 aswell, is this correct.

This is a bit confusing.

Do you have HT on or off?

No, not necessarily.

Yes I have HT on but I believe I have worked out the affinity mask wrong as I have just use that tool that was linked earlier and I used the expert mode.

 

Selected that I have 4 logical cores & 4 threads. Gave me an affinity mask of 2047.

2047 is wrong. That would be for a six core processor.

 

Just for now try a value of 116 and see if things improve.

 

Then have a read of this long thread:

Try some of the other suggestions in it to find something that might work better with your system.

Well that tool that is linked about asks you to use expert mode which asks how many logical cores you have & how many threads.

 

In my case I have a Quad core so I selected Logical 0 thru 4 / Thread 1 thru 4......is that not correct? I will try 116 as I had 84 previously which I don't know where I got that from. On my windows task manager when I right click on P3D>Set Affinity it shows CPU 0-7 but only 3, 5, and 7 are ticked running under affinity mask of 84......will see how 116 goes.

No, it should be logical 0 thru 3 (0,1,2,3) / Thread 0 thru 3 (0,1,2,3).
