In short, it says that shader cache is one of the reasons for stutters. And if you delete shader cache every time you change something in cfg, or install new addon, you'll have stutter free performance.

To be honest, never saw any difference to performance/stutters when deleting shader cache, every now and then.

 

Opinions?

Sounds a bit like voodoo, but hey, if it helps to paint your CPU blue and turn it upside down, go for it.

 

I delete my shader cache before every flight.  The biggest change I notice with that is that I get fewer autogen spikes.  It *may* be contributing to reasonably crash-free performance these days.  I don't have a stutter problem and I don't remember the last time I did, so I can't help you on that one.

Maybe you don't have a stutter problem because you are deleting shader cache before every flight?

Gee, ya think??

 

Actually, I've never really had stutters, even on my older computer, and I don't know why.  It was only recently that I started deleting the cache.  Any stutters I may have had were in the really early days before FSX was tweaked properly.

 

What I do have is occasional screen tearing, panning around with Track IR, which I can ignore.  I suspect if I didn't have the tearing, I'd have stutters instead.  I can ignore tearing a lot easier than I can ignore stutters.

Would one do this "delete shader cache b4 every flight" ....if one had the Steve's DX10 Fixer installed?

I didn't quite understood this. You mean DX10 Fixer is deleting shader cahce on every FSX launch? I have DX10 Fixer, so I doubt. And in DX10 mode I'm seeing a lot of microstutters, before and after deleteing shader cache, so it's probably a placebo effect, as usual.

If you aren't experiencing autogen spikes (trees that are suddenly 5000 feet tall for a single frame), and FSX isn't crashing every third flight, I wouldn't worry about deleting the shader cache at all unless you change FSX settings or add or delete new scenery.  There may be other reasons as well. 

 

It's like chicken soup:  it may not help, but it can't hurt.   (See also "voodoo" and "placebo effect")
