Any ideas why using d3d instead of ddraw causes sound to lose pitch?

Rock solid so far, thanks for all your help Calamity

I would never guess that this is just a standard pc crt, perfect res, perfect sync and hlsl effects ;) 

Paradroid:
Photos? Would love to see what you're seeing!

HLSL can be pretty cool. I was really impressed with it in the beginning. Of course, I can see some of its shortcomings after spending lots of time with real CRTs. However, you've got a kind of hybrid setup going. Very interesting!

jimmy2x2x:
Well I thought I had it solved, then it returned on bootup.

I was running VNC server in the background for remote admin, removed this and it seems fine again (didnt think to mention it!)
I suspect this was the real culprit as it interfaces with something VNC mirror driver as a graphics device.

Paradroid: for me its an ideal setup I can run everything from very low res arcade game to street fighter iv in 1600x1200 at authentic resolutions and refresh rates - I will try and capture some decent stills later on, but I am very happy with the hlsl effects.

here is my current config:

Nothing over the top, scanlines, very slight pincushion and some over saturation (remember to switch video to d3d to enable hlsl)

Yes that makes a lot of sense now that you mention that, and is an interesting discovery as a possible source of erratic frame rates. It's also surprising that ddraw doesn't seem to be affected by it! I always preferred ddraw to d3d, it's a shame it's almost deprecated.
