TopoFusion on the HP 500 Slate

[Offsides]

Scott,
I've just gotten hold of an HP 500 Slate (Tablet).  It runs Win7, has 2gb of ram and a 64gb SSD.  I figured to make a super GPS out of it for use on our local Search and Rescue team.  With Garmin's 100k topo, BaseCamp pans around a map as snappy as it does on my laptop.  TopoFusion crawls.  While background tasks like downloads work normally, screen redraws are virtually static.  It can take literally seconds for the screen to recover from a 1/2 window pan.  Is it a VB6 issue?  I've got DirectX 11 loaded.  Any ideas?

Hey Bill,

That is an odd one.  In general TopoFusion is faster than Basecamp!  Something goofy must be going on.  I assume the graphics drivers are relatively up to date...

Maybe post the TF log (diagnostic file) here or email it to me.  There might be some clues there.

Thanks.

Scott,
I'll attach a couple of .log files to an email.
The HP500 is aimed at the "productivity" oriented customer, another way of saying it's happy running Word but not WarCraft.  Graphics speed is not high on the list of features.  I guess if you can look over the logs and pinpoint a hardware deficiency, that would be a start.

All indications in the log point to capable hardware.  TF really should run well even on the weakest of graphics cards... it even runs on one of my very old netbooks (one of the first). So something must be going on -- maybe search for a new graphics driver?

Lack of OpenGL support shouldn't matter.

Scott,
Ok, thanks for the log review.  I was hoping you could spot an "aha" that was easy to tweak but not finding a problem is good, too.
In the "underground" there is an Intel driver that may improve performance.  Unfortunately, it's not supported by Intel so nothing is certain.  I'll do a drive image before attempting an upgrade.  ;-)

Windows, up through 7, really isn't a very good tablet OS because all the buttons and other controls are mouse or keyboard-centric.  Still, if I can get TF to run on this little guy it should, hooked up to my 60csx, make a terrific field GPS.

Thanks for your help,
Bill

Scott,
An update on my "experiment".
I've installed the new driver with some interesting results.  First, the new driver enables 3D rendering in BaseCamp but very poorly in TF.  I won't go into detail, but it's unusable.  What's bizarre, though, is when you dip into 3D mode, then back out to 2D, panning is at full speed(!).  You have go through this little step each time you load TF; once done, you have the usual fast navigation.

I've concluded that both drivers are at fault.  The original one is purposely limited for some reason, the second is buggy.  I suppose that's as good as it's going to get as the HP 500 is discontinued.

Thanks,
Bill
