Yeah, I am not sure what the MMIO is about, but here at least there is a very real performance impact.
Sure, when comparing across different configurations what I am seeing in my 'slow' setup may not seen all that bad...however, the old IBM SNAP driver was pretty much able to keep up with my Win7Pro box which happens to have the very same Phenom II X6 cpu and ATI X850 XT PE video card in there (but in a different motherboard), so a fair comparison, and I for one was always impressed that my old OS/2 box was holding up to the Win stuff.
In my troubleshooting I did investigate the potential aspect of having 6 CPU cores enabled vs the old 5 core setup, this however had no impact on driver loading, same LOG entry, same performance results (+/- the CPU extra power contribution).
Anyways, I did log a ticket for the AN/SNAP folks, see =>
https://mantis.arcanoae.com/view.php?id=1505, the Mantis system appears to be down at the moment (I can not reach it) but I do not suspect they will be able to look at this anytime soon, I think Rich is busy on some type of dynamic resolution changing process (I do not know this first-hand, just picking up the stuff from the "ether"...LOL).
Alright, thanks for the feedback you guys. The next step on my search for the "Holy Grail" was to re-try the dual-head configuration. The AN SNAP drivers though still are running into the same problem as the IBM ones, which is declaring the monitor EDID to be broken, subsequently, as best as I can tell only the 'Head 0' drivers get loaded. This will have to wait.
ivan,
My Samsung 245T panel has HDMI connection on it, but I have not tried it. Will give it a go tomorrow and report-out. As it happens, playing with the SNAP drivers hasn't been the most fun event, I did manage to mess up my INI files badly enough that I needed to recover from a backup to get back to a working PMMAIL, FIREFOX and PSI install. Not sure what it was, however, PSI would produce a trap entry showing a SYS3175 in REGISTRY.DLL.
Ah, one more thing, given that we are speaking of other video driver/hardware related stuff: who has a working dual-head configuration? What are you using, can you post your GRAPHICS.LOG contents?
I am asking this last question because the SNAP readme clearly states that even the ATI hardware will only support DVI for a single display and anything else needs to use RGB. Indeed, my ATI card has two DVI connectors, I ran DVI to my primary but used a DVI=>RGB adapter to my secondary. I did end up seeing the following in my GRAPHICS.LOG file, however the 'head 1' panel never produced anything on-screen.
