Very low 2D GDI performance on AMD cards (2014-2018 release) = Bug Radeon driver

[radeonwin7bug]

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 v18.8.1 (all versions)
NVidia and Intel video cards there are no problems!!! Unfortunately, the problem low 2D performance is present on AMD cards only.

1) Reduced Windows performance and low FPS from the Radeon driver. On the "Standard VGA Graphics Adapter" - no problems.

Programs for the test:
2D Test with source code - Removed
SimpleGLUT with source code - Removed

Radeon driver v15.7.1:
FPS = 4 - 1100 (huge drawdown FPS)
Very large lags when moving windows.

"Standard VGA Graphics Adapter":
FPS = 510-720
There are no lags when you move the window.

2) Increase 2D performance from nothing. If you place the "Radeon Settings" window underneath the spectrum window, so that at least 1mm of the window is visible outside the spectrum window, then the spectrum is accelerated tens of times and the FPS in simpleGLUT rises from 40-60 to 1100-1300. AMD drivers can not determine the resources, which the program requires, and mistakenly sets the video card to minimum performance.

1) Compare 2D GDI performance - Discrette OLD vs Discrette NEW.

Experiment 1. Old card PowerColor HD4670 (2009)+ Catalyst v13.9

Experiment 2. New card ASUS Radeon R7 360 2G (2016) + Crimson v18.4.1

Resume: The old video card is faster.


2) Compare 2D GDI performance - Discrette vs Integrated.

Test #1: Discrette graphic card - Radeon R7 360. Very low performance

Test #2: Integrated CPU Intel i5-6500 - HD 530. Normal performance

Resume: Integrated CPU i5-6500 HD530 has higher 2D performance than the discrette Radeon R7 360.

What you posted here interests me.

Does this problem exist in windows 10 as well? How would a regular user like me run into this by accident?

EDIT: did not see test 2 integrated in your second post. but is there any other ways to run into this?

Imo, this just goes to show that driver support for Win 7 with those cards listed above is fading & vendors are focusing resources on win 10.

I just wanna say that I, and i am sure some others here if not all, are thankful for you getting this info out there but i am under the impression that this is a burner account.

Like whats up? is the CIA or KGB after you?

I'm nearly certain this is a spammer. He used a throwaway name, email address, and has spammed this on multiple other forums. I was going to leave their account alone until they started posting links to download files. The links have been removed, and I'll keep the thread open in case someone has an actual question here in the future.
