Windows 7: Very BAD 2D GDI performance AMD drivers (15.x - 18.x) on Classic theme

Very BAD 2D GDI performance AMD drivers (15.x - 18.x) on Classic theme

Very low 2D 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 v18.8.1 (all versions)

1) Installing RADEON driver reduces the 2D performance by 10-50 times.
Demonstration of foobar2000 and P-CAD on the "Standard VGA" and after installing RADEON Driver v18.7.1 with FPS measurement using simpleGLUT

Decrease in FPS = 750-780 to FPS = 27-54 (in the foobar2000 spectrum)
Drawdowns FPS = 1300 to 10 when scaling a drawing in P-CAD

2) The switch of video memory frequencies (150-1500 MHz) on the CLASSIC theme keeps the memory frequency at the minimum value of 150 MHz, even when the GPU load is 100%. At the same time, on the AERO-theme, even when the GPU is little loaded, the memory has already switched to 1500 MHz.

3) 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 -
SimpleGLUT with source code -

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.

4) Absurd!.. Increase 2D GDI 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.

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.
ABSURD!!! )))

Classic theme for Windows 7 with GPU acceleration "Classic AE mod 2019_6" (July 12, 2019)

Complete list of modifications:
1) Added a gradient to the window title
2) The correct color of the text in the active and inactive window titles
3) Normal Tahoma-font (without ClearType)
4) The correct gray color in all elements of the interface RGB (212, 208, 200)
5) Correct TrackBar
6) Classic menu (fixed color)
7) For a better view, the highlighted item on a gray background is darker than on a white
8) ProgressBar animation is disabled
9) No-skins cursors are used
10) Fixed a bug in ScrollBar
11) Fixed background color Windows Firewall
12) Fixed aero mode crach at 125% font size
13) Darker active window title in non-aero mode
14) Correct resource IMAGE#1136
15) Fixed text captions (white field in Outpost)
16) TaskManager and Calculator with a classic design are attached,
and additional programs recommended for use:
- 7tt_setup - very useful tweaker of the TaskBar
- ClassicShellSetup_4_3_1-ru - for classic "Start" menu
- FONTS_140516 - replaces the font Segoe 9 with Tahoma 8 in all dialogs
- Win7 Style Builder v1.5.0.0 - msstyles file editor, if you want to modify this theme

1) Install "UniversalThemePatcher" (Recommended) or "UxStyle" for your Windows 7 OS (32- or 64-bit). If "UniversalThemePatcher" or "UxStyle" is already installed - then this step is skipped. This patch allows you to add third-party themes to your system.
2) Unpack the theme "Classic AE mod 2019_6" in the path c:\WINDOWS\Resources\Themes\
3) Go to "Personalization" and switch to "Classic AE mod 2019_6"
4) Restart your PC. Enjoy the classic design Windows 7 with GPU acceleration!
