Few points to help increase fps, just had to battle my 4.8GHz OC which prefers to be 4.68 in summer as I just found.

 

1. Overclock is essential to run FSX with demanding addons such as PMDG.

 

2. When overclocking most people  never touch ICH IOH mobo voltages and I just found they helped put an end to app crashes that result when you OC and your hard drive is not got enough juice to keep up.

 

3. You need top top cooling so those voiltages can go higher and fps higher.

 

4. Try to use ssd for as much as possible especially OS drive. Try to spread stuff out across multiple drives, but the more drives you add the higher you need to make the mobo voltages mentioned above, so good cooling.

 

5.Always get a case with maximum cooling potential, bigger cases are better for more air flow if air cooling.

 

6. Always leave off 20/40% of your cores out of FSX, so you can have more and stable OC. example affinity mask 14 as mentioned,

 

7. Only way to avoid OC in this business is to stick to default FSX and lower quality addons such as justflight etc. I think justflight is just as good as PMDG sometimes cause their addons don't eatup everything you throw at them.

 

8.In my case PC hasd DIY pipe that moves hot air outside, and ther is standby portable AC to b low air in the case on hot days.

 

9.higher mobo voltages == higher fps == higher OC == super cooling.

 

10. My case is big tower, 2 140mm fans in front, 3 on top, 2 120mm fans in back all blowing air into case, and their is a heat sink that comes with its own 3 140mmm fans that blows air out the case into a pipe that takes the hot air outside.

 

with this type of case, and a portable ac to blow air into the top of the case when needed, heat is not a problem. my cpu voltage is above 1.54v and temps never get to 90%. 

 

 

 

 

 

In short get a good cooling solution, does not have to be liquid cuase am doing very well on air, and PC is easier to service on air cooling, and then you can play with voltages and clocks to get the FPS you want. Doing so in a confined case with lapse cooling leaves very few low fps options.

I agree with everything you said except this

 

." I think justflight is just as good as PMDG sometimes "

 

LMAO!    :lol: 

Keep in mind that the GTX650 despite being the newer card is fairly low end and actually less powerful than the 560.

 

Yep, was just about to post this. Bigger number doesn't = better performance. A 3 and a half year old GTX 560 will still destroy any of the low end 700 series cards even.

Target FPS is set to 30 and I've made the tests..

 

About AffiniityMask=14 or 15 or 84
I tried all of them in both "modified FSX.cfg" and in "fresh copy" 

After all tests I can say that in all conditions AffiniityMask=84 is giving the much more better result.

Gap is big; AffiniityMask=14 or 15 is decreasing FPS around 40%-50% when compared with AffiniityMask=84.

When I look to CPU usage the results are as below:

IF AffiniityMask=14 or 15,
Core1 ~= 90-100%
Core2 ~= 50-60%
Core3 ~= 50-60%
Core4 ~= 50-60%

IF AffiniityMask=84,
Core1 ~= 20-30%
Core2 ~= 15-25%
Core3 ~= 100%
Core4 ~= 70-80%

 

 

Theory and practical results are not matching here as I understand...I have no idea about why AffiniityMask=84 is giving better result. 

But I can see the FPS number and a smoother flying result by my eyes ???

 

So now I am keeping AffiniityMask as 84

I'm clueless as well but hey, whatever works is good!

I have never had to set affinity mask in FSX since I got Processlaso.

 

If the OP got processlaso you wount regret it, set affinity mask for FSX and about a thousand other features to improve your PC for

smooth sim. For example

 

1. it allows disable core parking,

2. move all unessential programs to cores not used by FSX, don't touch system apps

3. I Use throttling to reduce CPU use of hungary apps like weather programs, I use laso to throttle ASN, I prefer smooth flight to smooth weather.

4. No need for clever maths, just click the cores you want for each app such as FSX in nice window view.

5. information is retained after boot and you can set profiles

6.A big bonus is ability to set IO and Memory priority for apps, for example FScommander is set to lower cpu, iO and mem priority

7.

8.

9.

and much more.

 

Laso is a no brainer essential toolbox for any self respecting blue screen veteran.

But watchout this one can break your system if you tweak it faster than you understand it, so best start with saving the default profile and setting affinity initially.

 

Also no need to test if leaving cores off helps, if you gona OC it will allow you to OC higher, if you not in OC, then its less usefull.

 

In short FSX  has a flaw in its design that makes it starve the PC that is running it till it crashes, the more you OC the more obvious this becomes, and one of numerous ways to tame is leave some cores off, but that's not all, not by a long shot.

 

add small partreject ratio = 4

 

My system mostly set to Word Not Allowed's guide, and Bufferpools set to zero for years and never looked back, only pain is the 2xwater you have to use.

 

Did a test today that proved you can OC higher if you spread stuff out like scenery on a third drive, and even addons then on fourth drive, obviously system and FSX being first 2 drives.  With FSX running using windows resource monitor see what is busy on drives.

Hard drive is one of the biggest neglected bottle necks in FSX especially if you got Gigabytes of addon scenery to load.

My FSX  always used to crash on first load then work next time round cause its had chance to cache, that before I increased IOH, ICH voltages.

FSX is not just CPU Hungary its Hard disk MAD.

 

After several hours battling to stabilise my OC and failing, it occurred to me that my I7990 is worth about 3 times as much as my entire Gigabyte mobo, so maybe leaning heavily on the cpu clock rather than the base clock would help, so went from x31 to x36 on the CPU Multiplier, and this is how my latest OC got stable. also PCI clock is doing fine at 120, and stable with higher PCIE voltage. These are the bottle necks that cause app crash, cause if all sliders are down trust me you won't get app crash, I checked.

I like the bit about the flaw in FSX that starves the PC over time, classic.

Lol, as the topic shifts so does it's location. Time for the Hangar Chat.

STANS !

 

 

How can I switch off the moving jetways ?

I think its ,reduce scenery complexity bar in FSX settings
