Pete's OGL/D3D Driver 1.68 & P.E.Op.S. Soft Driver 1.11 Released!

JTex · December 3rd, 2002

Pete's OGL/D3D Driver 1.68 and P.E.Op.S. Soft Driver 1.11 were released today, you can grab them at Pete's Homepage. Here are the release notes.

03. December, 2002 Version 1.68

- Fixed a small bug in the vram upload detection, this
caused a strange flickering in ChronoCross with certain
Offscreen Drawing modes.

- Finally I was able to get Final Fatasy Tactics, to investigate
the 'missing world map' issue, which was reported by some
users. Well, that issue was no real one at all (you just need
to set the correct framebuffer access/texture options to see
that map), but the game showed me another small
bug, which was in my plugins since ages: sometimes the 'fast
palettized tex windows' option caused (wrong) transparent
textures. Fixed. Ah, and no, it doesn't mean that now TNT2 or
ATI cards can use that option, it simply means that a few
text boxes in FFT are now drawn opaque, the way it should be.

- And now the biggest chance: frame skipping. Ah, Lewpy's old
skipping code hasn't been improved since I've added it in
gpuPeteTNT version 1.11 (released in May 1999!), so it was
really about time, eh?

Well, good frame skipping is a bit tricky to do, the old method
tried to measure the average psx frame rate, and skipped every
second frame if the speed was too slow... yup, some speed up,
but not very accurate.
The new skipping will measure each drawn frame, and decide
automatically how much skipping is needed to get the right
speed... if you use it together with frame limitation (really
recommended!), you will most likely get a correct speed in every
situation: doesn't matter if you had 15 fps or 40 fps without
skipping, or if speed was dropping only in certain situations,
now you should always reach the magic 50 (PAL) or 59.94 (NTSC)
framerate if you are enabling frame skipping + frame limitation
together (well, there are some limits: if your system is only able
to reach 1 or 2 fps without skipping, forget it).

Of course there are still some things to consider:

* Frame skipping will cause glitches/missing stuff in some games
(depends how skipping-friendly the game has been coded).
And most likely your favourite game will be one of them. That's life.

* Skipped frames make a game more 'jumpy', less smooth. You will
not notice that very much if just a few frames have to get skipped,
but the more, the uglier, of course.

* The plugin FPS display (at least in my or Lewpy's plugins) doesn't
show the real PC gfx card frame rate, but the vsync count of the
emulated psx gpu. Therefore:

* A big frame rate (higher than 50/59.94) doesn't mean a smoother
display, it only means a too fast game play (and usually screwed
sound). It's not like in a PC game, such games can draw additional
frames, if your system is fast enough. In PSX emulation your goal
should be a steady 50/59.94 frame rate, nothing more, nothing less.

* It's important that the main emu is generating the correct vsync
timing. Otherwise the speed will be wrong. Luckily modern psx
emus like ePSXe usually have the right timing, only in a few cases
the 'PC fps calculation' special game fix will be needed (that fix
is ignoring the main emu timing, but of course that will cause other
issues most times).

* Some spu plugins are offering a framerate limitation as well (done
with the SPUAsync interface, or by measuring the XA frequency).
If you want to use the gpu frame skipping, you cannot use such
external fps limitations at all.

Ah, and of course the golden rule: if you don't need frame skipping
with your system and game, don't enable it!

- Also related to the new frame skipping: some motherboard chipsets
are having a bug with MSWindow's high performance counters (see
also the version notes for version 1.52, 26. August 2001). While the
plugin tries to correct that bug automatically if only the fps limitation
is used, the correction cannot be done with the new skipping code.
Therefore I've decided to add a new special game fix, called
"low-res fps timer", which will fix that issue on that systems (by
using a different, less perfect, way to calculate the times). So, if your
system is having some weird timing behaviour, try the game fix, and
check out if it helps.

03. December, 2002 Version 1.11

- linuzappz repaired the 2xSai modes for 15 bit color depths.

- Pete added an improved frame skipping for slow systems.
For full details check out the 1.68 version notes of Pete's
hw/accel. gpu plugins, here's only a small summary:
* The 1.10 screen flickering with frame skipping will not
happen anymore
* Still: frame skipping will cause missing graphics in some
games
* For best results turn on skipping _and_ limitation. Try
to reach a steady 50 (PAL) or 59.94 (NTSC) frame rate.
* For buggy motherboard chipsets: activate the new 'low-
res fps timer' game fix.

Looks like kane did it .......

Anywayz reopening the thread.

Good news indeed!
Will perfect PSX emulation somehow arrive someday?

I would did that long time ago, but Im not that level to face the other staff members

Napro · December 4th, 2002

i love this new plugin version great job pete (whoever tha hell that is)

**liquid** · December 4th, 2002

The new frame skipping feature is fantastic! Woohoo, now I can run S2xSai image enhansing modes much smoother now

way to go pete!
