Hi.Sometimes on longer flights with fx. the PMDG MD11, FSX freezes and the only way out is CTRL+ALT+DEL. O&O have a product called "Clever cache" which should empty the cache and that way you should not experience these "freezes". At the product page one of the screenshots are with a profile for FSX.Any experience with this product anyone?

Never heard of it. Is your equipment overclocked and with good cooling? Sometimes it may freeze to relieve heat stress. I´ve had to back off on my GPU overclocking to stop crashing some of my games.

I have it, but have yet to reinstall it when I reformatted my FSX boot. To me the best way to stop freezing was the HIGHMEMFIX and keeping the GPU cold enough to prevent a nvidia driver crash. Now that you brought it up, I think I will reinstall it and give it a go and see if I see a noticeable performance and stability bost (not sure how I will figure it as my FSX installation seems to be running quite smooth at the moment)

My hardware is mentioned in my signature. It is not overclocked and in a normal ventilated environment. Could it be a heating related issue? It is not every flight that freezes.

Is this DX10? Did you apply the uiautomationcore.dll fix?

This is DX 10. No I haven´t applied the uiautomationcore.dll. Is DX 10 related to the appcrash issue? As far as I remember, the last time I had a freeze issue it wasn´t this appcrash.This is how O&O describes the clever cache program on their website:"even with the latest hardware, the processing of digital pictures, videos, games and constant server loads can often lead to longer answering times or "frozen" programs. In fact, it’s often not the lack of main memory capacity that’s at fault, but the file cache management of your Windows operating system. O&O CleverCache makes sure that the file cache is reset while the computer’s running: something that otherwise usually requires a restart of the computer. O&O CleverCache will let you will continuously maintain maximum levels of performance on your computer – no new start required, and with just a few clicks of your mouse.O&O CleverCache prevents those infamous program and application “freezes” where usually only closing the program with the Windows Task Manager can help. Simply install O&O CleverCache and let it take care of your computer or servers memory management."Based on this description I think it could be interesting to try it out, but I would still like to hear if anyone have had good experience with this.

Maybe You should try uiautomationcore.dll before buying any software? Freezing FSX on W7 is known issue and uiautomationcore.dll is the solution to this issue.More info and link to file here.

Ok thank you, I will try this.

I'd also stay away from DX10, its horribly flawed in FSX and will cause crashes.

What this O&O product does relates to the way Windows caches programs into memory and off the hard drive - I highly doubt this is the cause of your freezing with the MD-11. It's much more likely that you're experiencing a CPU or GPU overheat or the uiautomationcore.dll issue.

Thank you for your replies. I have just cleaned the fans on the GPU & CPU. Then I Will move the pc from the floor to my desk. Next I'm going to apply the dll. and have a nice long flight in the MD-11 without dx10 and see what happens. I'll get back with a result.

Ok, just did a flight from EKCH-OMDB (Copenhagen-Dubai) in the md-11. Took approximately 6 1/2 hours with fs2crew, REX 2.0, RC4 and lots of coffee. No problems at all :0) Soon I will try a longer flight to see if everything keeps stable, but so far so good.

The importance of keeping the inside of the computer clean is really something many underestimate! It keeps the volume and heat down which of course is of great concern when you overclock. I once helped a friend who kept a computer in the barn to monitor something with the milking process. It had been kept in the same spot on the floor for several years and he wondered why it had started making strange noises... When I opened the case... well.. I got a very graphical description of what "when the ###### hits the fan" means.

If you want to stress your PC above normal use just to see if there is any stability problem, use programs specific for stressing like Prime95 for CPU stress (don´t remember the name of the one for GPU stress, but there is one). They will use your resources way over normal gaming sessions and will show if your PC have some problem.

Furmark is decent if you want to heat up your gfx card
