Will Aero affect performance?

Recommended Posts

I'm not a fan of Windows 7's Basic theme, but every flight I do with FSX, it reverts the system from my Aero theme to Basic. Good news is I recently came across this tweak / fix to prevent FSX from disabling Windows 7 Aero: http://www.flightsim.ee/freeware/fsx-scheme-fix

 

However - will this affect performance? (eg. drop frame rates, stutter... etc) Note that I'm running addons like FS DreamTeam airports, PMDG, ASN, REX, ORBX, Aerosoft Airbus X Ext.

 

Thanks,

Hank

No issues running full screen and Aero here Hank. I am not a fan of W7 basic either, and I use the tweak you linked too.. I also use an affinity mask in the fsx cfg @15 and my fsx is smooth as butter, using unlimited frames. No stutters at all FSDT and flight Beam airports etc.

Glad to hear Julian! Thanks for your reply; I'm installing the tweak right now.

Currently in cruise; performance is, indeed, smooth as butter! I can finally, after all these years of reverts to the basic theme, continue to use my PC with Aero theme enabled while doing a long haul. Thanks again for your input.

No problem Hank. I think having Aero enabled seems to help performance.

I still run win7 like XP - classic start menu with opaque menu bars and task bar

I ran FSX for years in Win 7 basic mode, since it was supposedly incompatible with Aero, and indeed, disabled Aero on startup.

 

I have recently been running the sim with Aero turned on, primarily because Aero has to be enabled in order for Vsync to work with FSX in windowed mode.

 

I'm not using the modified FSX.exe from the site in the linked article above - I'm doing it via FSUIPC, which runs a small batch file to turn Aero back on once FSX begins loading.

 

In any case, have noted absolutely no problems whatsoever. Frame rates are good, VAS useage seems unaffected, windowed Vsync works of course, and if anything, the tendency to stutter when flying in a graphically intense area seems reduced.

 

Indeed P3D requires Aero to be enabled before loading the sim, as it won't work properly without it.

Hi Jim B.

I read your reference regarding Vsync in windowed mode. I have

[GRAPHICS]

ForceFullScreenVSync=1
in my FSX.cfg to prevent tearing of vertical objects while panning horizontally.  I've done nothing to enable Aero while running FSX and have no tearing in either windowed or full screen mode.  Can you elaborate?

EDIT. I'm wrong.   I originally checked the Moooney Bravo for tearing in both modes and saw no tearing in either.  I checked in the C172 and tearing was clearly present in windowed mode.  Now my question is what other changes are required to eliminate the tearing in windowed mode besides enabling Aero?  My question is largely academic as I seldom fly windowed.

My Fsx never forces basic theme on? Is this just if you run full screen?

To get vsync to work in windowed mode, you will need the line ForceWindowedVsync=1 in your FSX.cfg, along with the Aero re-start after FSX initializes. The restart of Aero can be accomplished via FSUIPC, via the modified FSX.exe from FSEstonia (though I'm not sure it's entirely legal to redistribute a hacked FSX.exe as they do), or by a couple of other methods involving batch files.

 

If you google "FSX windowed vsync", it should take you to several YouTube videos and online articles that discuss the various techniques.

 

AFAIK, Aero is NOT required for vsync in full-screen mode.

 

I also have vsync enabled (at 1/2 monitor refresh rate) in my FSX profile in NVidia Inspector.

No, it doesn't hurt anything, in fact it helps by enabling better Vsync support in windowed mode. I use Word Not Allowed's method with FSUIPC of getting it to pop back into Aero mode after the sim launches.

 

Aero basically makes the entire Windows desktop run in 3D mode - Vsync has problems if a game window is 3D mode and the rest of windows is 2D mode, which is what happens by default when Aero gets disabled.

Lol amazes me  that my post 8  got  a dislike for just installing  this helpful tip that the op has posted.

Don't take any notice Pete. It is user "StubbinMyToe" who also dislikes any post I make. The guy claims to be in his 50's but acts like an 8 year old. He is a stalker, of the internet variety.

 

Maybe the mods might remove the ability for him to vote a post, if he continues.

Affinity mask 15 on a quad core is the same as not having affinity mask at all,  as it has all cores selected. Its teh default setting.

This what all the guru's in P3D2 and DX10 are saying to use now.

Yes, because p3d is different and LM set it to use only core 1,2 and 3 meaning af=15 forces p3d to use core 0 as well.

Shouldn' it be 254

Ok, cheers Glenn. I am no expert on these things. I always had it set @14. I have been using @15 for the last week and having very smooth sim, including heavy areas ( In DX10 ).

As I only run FSX  on my fsx machine and everything else on a laptop,  do I benefit from using all cores ?

This is one of the greatest FSX tweaks I've found. Thanks to the OP for posting and for everyone's input.

 

Finding no problems here in the sim and less graphical glitches in the windows gui while FSX is running. Plus FSX looks really nice now in windowed mode. Talk about a fresh coat of paint.
