I've encountered a peculiar issue. About a day ago I got REX Essential Plus Overdrive and installed the full package of textures, intending to retain use of AS2012 for my weather generation. What ended up happening was that I received dreadful FPS reductions everywhere. At first I thought this was from using HD cloud textures, but loading perfectly clear skies with no weather elicited no improvement. Further reduction of global settings again proved fruitless. A full return to the backup textures that REX saved on my initial install again, oddly, lead to no improvements. I then went and reinstalled my last AS2012 texture preset, exactly as it was before I installed REX. Everything looked like it was before but my frame rate was basically never above 10 when using the NGX.

 

I then noticed something that wasn't the way it used to be. Its as if the REX textures I installed included some kind of lighting effect which was not returned to default when I used the backup, and again was not overwritten when I installed a new AS2012 texture profile.

 

Best I can do is show you.

 

 

 

As you can plainly see from the second image, everything is incredibly bright and only returns to a normal appearance once the textures pop in. The NGX VC is also noticeably brighter than it used to be when it was just showing the polys and not the textures. It used to be more grey, but now it looks washed out by a massive brightness. In addition I wasn't able to capture any shots of it, but when I switch to exterior view, if I have lens flare and bloom lighting turned on, the exterior model of the NGX and other objects glow so bright as to appear like the sun until the textures pop on. The default FSX push back vehicles just look like glowing balls of plasma til the textures load.

 

I cannot figure out how to revert to what I had before, nor do I have any idea what was changed. I'm probably going to reinstall everything, but hoping maybe someone knows whats happening I'm gonna leave this here for a day or so until I get the time to do a full reinstall. I was pretty happy with my configuration before this, and it doesn't seem like the HD textures are culprit as the frame rate basically remains exactly the same no matter the textures I install. My computer is about 5 years old now, but its a dual core OC'd to 3.66, and I have 4 gigs of ram with Win 7. I was getting very playable frames even in add on scenery airports like FSD JFK, but now those places are just 2-5 FPS while a bare bones default FSX airport is more like 10 max, and even cruising at FL390 over barren land gives me only around 10-12 FPS which tells me I'm just losing a lot from the "lighting" thats hitting the VC and my exterior model.

 

Since neither REX nor AS2012 offers an option to revert to default FSX textures and settings, only what was there last, I'm probably SOL, but even so if I can know whats happening maybe I can deliberately back the affected files up for the future, or else I"ll probably be slaved to a Windows Restore Point.

 

Any advice or help would be appreciated. 

I've been using REX since it was first released, and never come across an issue like this before.

 

If I were you, I'd speak to the lads over on the REX support forum, they are very friendly and helpful.

 

If you haven't already of course.

 

P.S One thing you could try is Windows System Restore. Restore to an earlier time before the issue occurred.

 

Some turn off System Restore, but to be honest, it's saved me a ton of hassle over the years.

best bet  as  to do as  martin has  suggested,  put your issue  in the  rexe  forum  making  sure you  put it in the correct thread. You will get  support  quickly, might be  an idea  to see if  anyone  else  has the same issue  as you have   by checking the forum

If you navigate to your main FSX folder and order files by date modified that can really help with finding files recently changed that might be causing problems. Out of interest have you tried FSX without ASE or anything running in the background and also check the FSX folder for the file D3D9.dll which can modify FSX appearance but also have a negative effect on performance.

I tried running everything bare, and the issue persisted. I flipped my cfg settings around a bunch, and oddly the issue went away. I'm considering that some custom change I made months ago to my config was erased somehow in some other change and I reset it.

 

I'm not sure. I wasn't very scientific in my poking around. All I know is that my frames are mostly returned to normal. I'm rather confused, but lately I've found that some things start working randomly for me. I'm still a novice with FSX configs so we'll see if it resurfaces.

 

I suspect perhaps it may have been nothing to do with REX, or the act of installing so many textures just reset something. I'll keep poking around, but its a strange ambivalence I feel now.

 

To actually come to understand the problem would mean it resurfacing. I'm kinda tired of troubleshooting. We'll see. 

 

Thanks for help.

This looks nothing like textures, rather over-stressing your GPU. If you are using hi definition textures from REX, simply back off the settings in the OPTIONS MANAGER inside of REX, then reinstall textures. See if this helps.
