AMD keeps silent about this bug. VERY low 2D performance - bug in RADEON drivers.
Compare "old GDI" 2D performance of two AMD graphics cards in one PC. The old video card is faster!
This bug all new cards - Radeon HD 7XXX, Radeon R5, R7, R9, Radeon RX 400, RX 500 series.

OS: Windows 7 SP1 Ultimate, built-in "Windows Classic Theme"
CPU: Intel i5-6500 3.2 GHz
Video cards: "PowerColor HD4670" (2009) vs "ASUS Radeon R7 360" (2016)

Experiment 1
Old graphic card: PowerColor HD4670 (2009 release)+ Catalyst v13.9
If the ACC is blocked***, then download video - http://ge.tt/7k4l1qp2
Rezult = Good performance.

Experiment 2
New graphic card: ASUS Radeon R7 360 2G (2016 release) + Crimson v18.4.1
If the ACC is blocked***, then download video - http://ge.tt/7gEc3qp2
Rezult = Low 2D performance. Slide show!!!

*** Account is blocked by AMD complaint.

Resume:
Old HD4670 (2009 release) in the 2D GDI mode has 10 times higher performance than the R7 360 (2016 release). It's buulshit!!!

AMD forum - https://community.amd.com/thread/227931
AMD developers is shamefully silent.

I appeal to all technical specialists!

To everyone who understands computer technology: a programmer, an electronic engineer, an engineer, please watch the video, where I demonstrate the bugs of the RADEON driver and tell me, what exactly can be the problem ???

Video demonstration on YouTube:

AMD complain about YouTube, hiding the problem. If YouTube account is "Blocked", please download this video from http://ge.tt/9NnRM6q2

I await your explanation of the problem.

Very bad 2D GDI performance on Classic theme Windows 7 - Bug in RADEON drivers.

This bug all new AMD cards:
- Radeon HD 7XXX;
- Radeon R5, R7, R9 series;
- Radeon RX 400, RX 500 series
with Radeon Driver - from Catalyst v15.7 to Radeon Crimson v18.6.1 (all versions)

NVidia and Intel card there are no problems. Unfortunately, the problem low 2D performance is present on AMD cards only.

AMD keeps silent and hiding this bug.
Forum - https://community.amd.com/thread/227931

1) 2D Test - 2D performance of aero and classic theme (bandicam)
http://ge.tt/4PfMw5q2

2) Demonstration of poor 2D performance on real programs.
Slow scaling of the drawing in P-CAD and lags of the spectrum foobar2000.
http://ge.tt/4xXdw5q2

3) Uninstall RADEON driver - increased performance in 2D GDI.
This is not a joke - it works so badly AMD driver.
Rendering time with Radeon driver is 140 ms and without driver 20 ms.
Software rendering of Windows faster, than "hardware" acceleration from AMD.
http://ge.tt/8UaRx5q2

4) The performance of the GPU is enough! The problem is the low reading speed from the Video memory.
On the Display is lags! But on the Bandicam video is not lags!
From Camera:

From Bandicam:

There are other demonstrations:
- Demonstration from another user on the Radeon R9 380. The bugs are exactly the same!
- Demonstration of the absence of problems Radeon R7 360 under the system Windows XP
- A video of the "denial" of the bug, shot by an AMD employee. Video - fake !!!
The video is made on the patched Windows 8 system, under the Windows 7 interface.
After the exposure, the fake video was deleted, but I saved it.

Take it to YouTube and leave it there, or spam AMD's Face Book if you must annoy someone.

For a start read the forum rules regarding triple posting.
Secondly be better at explaining , what you're issue is.
Third list the affected system correctly ie specs and Os version.

You Probably got shit Spec PC that's incapable of running decent Card
I Have no Problems with any of my AMD Cards
I had no problems from my 9700 Pro 9800 Pro 1950 Pro and my 290.

Aero under Windows 7 would run fine on my 1950 Pro and it would run fine on a 9700/9800 Pro
