Thanks guys.
The problem might be unique to my setup then, which is slightly unusual itself, but the problem is totally repeatable.
i.e. Load 190.38 drivers I get the problem (all the time), replace them with 186.18 drivers and the problem goes away.
It's related to having "Bump Map Terrain" & "Detailed Water" selected, but as I say, works fine with the 186.18 drivers.
Some more screen shots:
My setup consists of a home built system:
Intel Core 2 Extreme QX9770 CPU.
ASUS Striker II Extreme motherboard.
Kingston HyperX Memory - 2 GB.
Two
ASUS EN9800GX2/G/2DI/1G Graphics Cards.
Three
Dell UltraSharp 3008WFP Monitors.
The CPU, Motherboard & Graphics Cards are all water-cooled. I usually run with an 1800 MHz FSB and the CPU @ 4.05GHz. (I've tried dropping back to stock 1600/3.2, still the same problem)
I have Several Western Digital VelociRaptor Hard Drives, 300 GB, SATA 3 Gb/s, 16 MB Cache, 10,000 RPM
The internal hard drives are mounted in a
Removable Rack system.
i.e. I can shut down, swap drives, start up what is effectively a different computer. I have a drive just for Photoshop, one for Office, one for FlightSimX, one for messing around with Vista etc.
I'm using the
SoftTH "triplehead" v1.09 rc1 software to run the three screens (resolution 5000x2560) which up to now has been running very well.
I've currently got three drives dedicated to Aces High while I play around with this.
All three have a clean install of XP Pro (updated to SP3 + High Priority updates as of today). A lot of the windows "services" are disabled (the same ones on all three drives) such that there are 14 background services (not including taskmgr.exe) after startup.
All the Windows "components" are all removed i.e. Messenger, Media Player, etc and the only other programs installed other than AH are the "Hotas Cougar control panel", "CH Control manager", & "TrackIR 5".

DiskC_DxDiag.txt DiskC_video8.txt DiskC_SoftTH.txtWith "Bump Map Terrain" the land and sea is overlaid with a black mesh
and with "Detailed Water" the sea flashes from dark black to illuminated bright white.
These were all taken while using the SoftTH software
i.e. at resolution of 5000x2560
If I disable the SoftTH software and go back to just using the center screen, the problem remains.
at the stock resolution of 1600x2560
Not a show stopper for me, as I can just continue using the 186.18 drivers
I'm just intrigued what has changed to cause the problems for me with the 190.38 drivers.
