Problem with Graphics

[Anonymous]

Hello everyone,

I have a serious problem with graphics in Autocad 2018. It happened a few days ago while ı was using 2015 version. So I deleted it and replaced with 2018 version but still, I have the same issue. Colors changed as seen in the images. It is solved when disabling the hardware acceleration but this time line command and cursor move very slowly. It is like I am drawing on a very old computer. I have a strong graphics card. Please help me with that.

Lenovo Thinkpad E560

Intel Core i7

AMD Radeon R7 M370

8 GB RAM

WHEN DISABLED MODE: COLORS OK BUT DEADLY SLOW.

Strong, but is not working perfectly with Autocad.
Your Hardware is not certificated, right?

If the above tip for a certified or approved driver from Autodesk does not help, try your Lenovo and see if they have newer (or older) drivers that can help.

instead of shutting off Hardware acceleration, try shutting off each of the individual options until the problem is solved, and also at the same time make sure that AutoCAD is still functioning normal speedwise.

Thanks for the reply. When hardware acceleration is enabled, I shut down each individual option but still, colors change in place of another.

Thanks for the reply. No, it is not certificated. But with this laptop, I have been using AutoCAD for 10 months and never had a problem. I will try to install another version of graph card driver.

Hello

Have you tried to run with HQGEOM = 0 ?

On 2015 ok, but so it should been working in 2018 99% too.

Acad is using the AMD Radeon R7 M370?

aso.

When using M370: Try your onboard chip, you should have an onboard Intel HD Graphics 520 chip.
(Radeon is much better, but it doesnt help when Problems appear with Acad - chatch the straw)

But at this Point I cannot help you, my english is too terribly. Sorry, I'm out of here.
Google for switch between M370 / HD520
