New Nvidia tools and crossvendor GPU instrumentation info!

Following last days Scenix 5.5 or 5.6 release now I have found:

SceniX 1.6.5 (11 December 2009)
also old news (?):
PerfKit 6.6: added GT21x metrics support (so D3D 10.1 and OGL 3.1 extensions also no?)
but still old Linux PerfKit 6.0..
I tested with Ubuntu 8.04 (no newer kernels support for it..) so no Unbuntu 8.10 and higher..
also I think needs as Windows Xp special instrumented drivers and Perfkit 6.0 drivers still not support GT200 arch.
hopefully one guy has backported support for newer kernels support for this driver.. but this can't fix the lack for GT200 no?

some guy uses PerfKit for getting GPU load on Windows x64 with plots but as I have said him it's also now in GPU-z 0.3.8..
the problem with PerfKit is that it's need to install Perkit SDK (runtime?) which is a no small download..
at least Windows Vista and higher come with integrated support for it in normal driver buils.. so no more downloads for normal users..
remember Windows XP needs special driver that is shipped with it so not so timely updates..
You have to enable instrumentation with a toolbar..
Also remember gDebugger needs it for gathering exntended info about Nvidia cards..
Both for Linux and Windows..
gDebugger Mac accesses luckily cross vendor OGL metrics by Apple drivers (?)
Also note I have had issues with gdebugger in x64 Windows with Nvidia instrumentation files as gDebugger was only Win x32.. I need to copy some Nvidia instrumentation DLLs from System folder to gdebugger folder or move between System and SysWow64.. you check more fast all this with included demos..
ATI instrumentation is similar.. it's built right into the drivers for Vista and higher drivers and gDebugger uses it.. the problem with Catalyst is that some releases work some not.. I think 5xxx 9.10 or 9.11 ok..
The problem that ATI support in gDebugger is Win MAc only so no Linux?
well I don't know if it's the same but for OpenGL at least you have a Catalyst extension providing metrics for OpenGL also in Linux
Also getting GPU load is better in Nvidia now with mem load but ATI load is in ADL so public(?) and also Linux compatible?
have to check if OpenCL and DirectCompute affects load metric as Nvidia..
Need to check also GPU video acceleration metric wih Nvidia with Bluray and CUVID (nvidia sdk) and CUVENC (use CUDA h.264 encoder mediacoder) stuff..
