Package: pcsx2
Version: 1.5.0~gfc1d9aef0+dfsg-1
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Normal usage, beyond firmware dump (i.e. a game itself, post-boot)
* What exactly did you do (or not do) that was effective (or
ineffective)?
FAIL: Initially tried changing from HW to SW render (eliminates GPU)
FAIL: Disable/enable XFCE compositor and options.
SUCCESS: Rolled back to version 1.4
* What was the outcome of this action?
Worked perfectly. Complete success.
Also fixes bug #864008 on my system.
* What outcome did you expect instead?
N/A
* Bug recreation, and bug fix:
0) Foreword: You will have to play enough of a game to use the
game engine's PS2 hardware render capabilities. It is highly
recommended that Tekken 4 or a similar "engin-ed" game be used.
Finally, a testing machine should be >= mine: Ryzen 3600X CPU,
2x4GB DC memory clocked at 2666Mhz, AMD RX460 2GB video card.
1) Install pcsx2 1.5 on a regular Debian 10.x AMD64 system.
2) Try to run the game (see notes at point 0) through until the actual
realt-time 3D rendering begins as pre-rendered FMVs, and 2D planes
don't not produce this bug very vissibly (if at all).
3) After exhausting settings/fiddling: Bug has been recreated.
4) Purge the package pcsx2 1.5.x, NOT its dependencies.
5) Download the 1.4.x deb package from 9 ("Stretch").
6) Install pcsx 1.4 deb with dpkg (deps from 1.5 work)*
7) Ensure all settings are at stock. You may need software rendering
for Tekken 4 and similar.
8) Run PCSX2 with your game. It should now run at 100% FPS.
Bug #864008 is _also_ fixed by this method.
* Final notes
Please roll back to the 1.4 branch of PCSX2. The developers' last
"Release" pre-compiled binary is 1.4. Even Arch/Manjaro, known for
being "Bleeding Edge" use the 1.4 version. Clearly 1.5 is buggy, at
least on GNU/Linux.
Though PCSX2 is supposedly "cross-platform", I see a lot more
development and patching for M$ Windows, likely because the audience
is bigger, giving them more testers and a larger target "market".
As of writing, version 1.4 shares the exact same deps as 1.5.
