Double-buffering bug RADEON drivers on Windows 7
Classic theme or Windows Basic theme (no AERO themes)
This bug all new AMD cards 2014-2019 years:
- Radeon HD 7XXX;
- Radeon R5, R7, R9 series;
- Radeon RX 400, RX 500 series
with Radeon Driver - from Catalyst v15.7
to Radeon Adrenalin v19.1.1 (all versions)
NVidia and Intel video cards there are no problems!
Unfortunately, this problem is present on AMD drivers only.
Using "double-buffering patch" increase RADEON driver performance up 10-30 times! Demonstration in the foobar2000 spectrum with FPS measurement using simpleGLUT.
No patch (WS_EX_COMPOSITED = OFF)
FPS = 25-60 (very big lags)
Used "double-buffering patch" (WS_EX_COMPOSITED = ON)
FPS = 850-920 (no lags)
