Hi everyone, I'm having a bit of an issue here. I've had the same computer for a fair bit of time at work here and the hardware has not changed, however I did get a recent upgrade to Windows 7 about a week ago. I noticed that there was a fair bit of "lag" when I was drawing lines with dynamic input on, so I turned it off to help with the situation in the meantime, but the issue of hardware acceleration is a weird one. For some reason, even though the same hardware is present, I can't get AutoCAD LT 2012 to even detect my video card. The drivers are installed properly, as noted in the device manager in Windows, and I understand that an onboard Intel chip isn't exactly the greatest, but the point is that I had it working for Windows XP without a problem... it just seems weird that with an upgrade to Windows 7 that it would just not work anymore.
Under my display adapters in the device manager it lists "Inter(R) HD Graphics", and the driver version is 9.17.10.2932, which when I click the update driver button claims to be the most up to date driver. What's strange is that AutoCAD isn't detecting anything at all for my 3D Device... I'll copy paste the Performance Tuner Results Log:

I'm not sure what else I need to say to make this matter more clear, so if there is any additional information needed, please let me know. But, otherwise, I'm stumped. Any and all help would be greatly appreciated. Thanks in advance!
There's a huge performance hit, it's quite noticeable. It was noticeable even in windows xp, but I was able to turn on the hardware acceleration and it was fine.
I can't actually remove windows 7, it's a work computer and I have no choice in the matter as our entire network is being upgraded.
Not "remove WIndows 7", just the update that broke LT: why would I ask you to remove Windows?
Then turn off automatic updates: ask your IT how to do so.
Also, please ensure your LT version is fully updated and patched. it may help/
Just so we're all clear on what you are saying: you had Win XP, it was *replaced* by Win 7. Is that accurate? If so, then its not merely an upgrade.
The only update that occured to "break" the hardware acceleration was the upgrade from Windows XP to Windows 7, so I thought that's what you mean. Apologies, I didn't know what you meant.
How do I know if my version of AutoCAD LT 2012 is fully updated and patched?
I then also misunderstood.
LT2012 works fine in Win7: but it must be correctly installed and not 'left in place' when Win7 was installed.
Autodesk recommended uninstall/reinstall procedures are as follows
Uninstall: http://usa.autodesk.com/getdoc/id=TS45252
Ensure the user installing/uninstalling and using the product have enough rights to do so (install and reinstall as local administrator):
Unable to run AutoCAD® as a restricted user http://usa.autodesk.com/getdoc/id=TS1055299
More complete .NET fixes if you did not go through this procedure:

Just as an update, I am still having nothing but problems with hardware acceleration. I've downloaded AutoCAD LT 2012 from the links provided above and used my serial to activate, and that went smoothly. I downloaded and installed the latest Intel drivers, which were released back in August of this year, I believe... and after updating my drivers and installing the latest version of autocad lt 2012, I am still unable to turn on hardware acceleration.
I really don't know what else to do. Seems weird that it would work with windows xp and then when I install windows 7 on the very same computer, it stops working properly. Weird.
Yes it is weird that the change in OS has left a peristant problem with yout LT 2012 software.
This is peer support and if we had something for you to try we would have done so.
Sorry to keep you waiting.
