Hardware Acceleration Problem

[Anonymous]

When ever i turn the hardware acceleration on, colours on the screen change. I have attached two screenshots of it. Anyone knows what's the problem and how to fix it ?

Hi,

>> Anyone knows what's the problem and how to fix it ?

There are two options today:

• install a newer (or older) graphic card driver
• wait until Autodesk releases an update with a fix (the inverted colors happened already to some users here so I guess Autodesk is working on that issue)

Sorry for not having better news.

Hi @Anonymous,

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

I am sorry you are experiencing this issue. As @Alfred.NESWADBA, several threads have started recently with this issue.  Can you share some information with me so I can get it to QA?

I would like to know your:

Windows Version (winver)

AutoCAD version (_vernum)

Graphics card make, model and driver version

DirectX Version

Please also take a screen capture of the GRAPHICSCONFIG window.

To give me even more, you could prepare a NFO file for me to examine.

Hi @Anonymous,

It appears that there is a newer driver for your graphics card.

My Windows build is 15063.540 which appears to be slightly newer than yours - I suggest checking for updates to your OS.

If you are willing to take the time, I suggest you remove DirectX12 and put DirectX 11 onto your computer to see if that alleviates the problem.

I checked for updates and it shows everything is up to date. Even updated autoCAD to the version released 2 weeks ago. Didn't work !!

Hi @Anonymous,

Thanks for the update. Did you also try removing the DirectX 12 and installing 11 to see if that will help the issue?

So i checked and found a software for updating directX directory. There were some dll files missing. The software filled in those files and now my autocad is working fine.
