A HUGE improvement in FPS.......

[Glenn]

To anyone that has followed my problems with very low framerates (4 fps) recently. I found some improvement when I installed MSI Afterburner, which saw rates jump up from around 4 fps to around 18 - 20. Just now, I thought I would try something different. I right clicked on fsx.exe and opened the properties / compatibility tab. Just for the hell of it I ticked 'run as administrator' - even though I am the administrator and only user. Then I thought that, as a "what if" experiment, I would also tick 'compatibility mode for windows XP3 (service pack 3), and also 'Disable display scaling on high DPI settings'.

Then I ran the exact same flight that I have been using for test purposes. And lo' and behold, the fps rates have jumped right up from around 20 to around the 50 mark !

I have absolutely no idea why such small seemingly insignificant changes should have such a big effect. Maybe might be worth someone else ticking those boxes just to see what happens?

The fps on an HD movie is 32 fps.

Can someone with working tweek make some video like my showing internal FPS counter without tweek and with tweek aplied. For best heavy location will be perfect. KLAX-KONT at best :) All of us, which have no impact want to see your FPS gain...

Thanks.

It is reaction to me? I do not know what you mean. Video frame rate doesn't correspond with FSX frame rate. It is recorded with Shadowplay at 30 frames per second, 20 Mbit bitrate.

but it does. FPS means "Frames per second". The graphic picture on your screen is being changed at that rate, creating the illusion of movement.

If you have a frame rate of 8 in FSX the scenery will move at about the same speed of an old 8mm movie film. Visible jerking movement will be seen.

If your fps in FSX is 20 the scenery will move smoothly, much like a 16mm movie.

If your fps in FSX is 30 or above, scenery will move very smoothly, close to a 32mm movie.

There is also a limit to how many fps your eyes can see. It varys per individual.

This explains why some people are quite happy with 20 fps and others are not.

It might. But the numbers are far to low. The problem is: a movie might have only 24 images per second, but as it was already recorded like that, you have a significant amount of motion blur in it, rendering faster movements smooth although the 24FPS are quiet slow. In a computergame, you have 24 absolutely clear pictures, no motion blur at all, that's why it still seems not as smooth as a movie with the same framerate.

Just some links, I think everybody is capable of seeing the difference between 30FPS and 60FPS when motionblur is deactivated and how motionblur helps to get the impression of smoothness also for low FPS counts. FSX, FSX:SE and P3D obviously do not offer motionblur...

no they don't but I wouldn't call the the pictures in FSX absolutely clear. Even on it's highest settings the graphics, especially buildings are blurred on purpose. You can see this by going and looking at the textures in their respectful folders.

Hd movies show one frame, followed by a black frame and then a repeat of the first frame before moving on to the second picture and repeating the process. (Wiki)

A fasinating subject for sure.

Well, those are rather just textures with a bad resolution than purposedly blurred textures. As a matter of fact, the blurring must be in the direction of the movement, you can not achieve this by a blurred texture, as you not always move along the texture in the same direction. Simply check the texuture folder of a HD scenery addon (ORBX, FlyTampa) and you will instantly see that there, every texture is absolutely crisp (2048x2048 or even higher). Motion blur in games is a post-processing effect not related to the textures in their native form.

WoW! Didn't think my original post would open such a - albeit fascinating - can of worms! Some inetersting remarks / information being written about.

Is there any evidence, by the way of screenshots or a video that changing the compatibility options actually have an effect?

After looking around online, it's well accepted that it makes no effect. This has me curious :P

[blewberry]

As with nearly EVERY tip/tweak. Configurations vary so much from simmer to simmer that it will work for some and not for others. Try it, if it works it works. If doesn't it doesn't. That's FSX/P3D for you.

It did not work for me.

Yes, I have same question that is reason why I did video with difference... Tweak cost me few FPS, so for me, that tweek not improved, but hurt my performance. Same as many other tweek, So I have applied just two tweeks...

Tweek 1. buy better hardware... applied twice in last few months and working well for me with huge performance gain

Tweek 2. delete FSX.cfg, start FSX and enjoy flying.

I currently run a 4690K oc'd to 4.0GHz, 8GB RAM, 290X GPU on a single display. And even while up in the air with no clouds, over the ocean in a default 737, I still only get a max of 25FPS. This stays consistant until I hit somewhere like Heathrow or LAX with the top notch payware scenery, then it drops to about 6/12FPS.

So you can't exactly say my hardware is bad. I've seen friends of mine with "worse" setups in terms of hardware, and still getting much better results than me. I've been trying for 2 years to figure this one out haha.

For fsx.. it all comes down to your processor. I was doing around 14 to 15 frames. with alot of sliders maxed.. then overcloced my from 3.4 to 4.5 ghz now getting 20 to 25... its' CPU intensive.. hopefully DT's version with have the GPU work way more.

I don''t have experience with AMD GPUs, but with GTX960 I had mostly 50FPS in Europe over small cities and villages and about 40 over bigger cities. With heavy clouds and 4xSGSSAA I had stable 30FPS locked. I think that 290X is much better GPU and can handle antialiasing much more... So there is some problem with you rig I think.

LAX area are more CPU related, but still 6/12 FPS is to low for 4GHz intel with your video card...

Yes It is CPU intensive but only for one core. If DTG make something with much optimized multicore performance, then performance problem will be solved, but I think it is not easy to do. P3D v2 is much more optimized but still, one core is overloaded and two cores are about 40 percent load only (with 84 affinity mas ok HT enabled i7, under 30% if affinity mask at 85).
