God of War 1 PAL sudden slowdown
#1
Hi everyone,

I'm getting 50fp/s on Gow1 most of the time
(using only recommended hacks), except for some tiny
slow-down areas where the framerate drops to 25 and EE drops from
~70 to ~50%, GS remains unchanged at ~ 20-30%. Even turning
frame-limiting off makes the EE-value drop to ~50 in a slowdown-area.

Is this a plugin-bug ? When I leave the slow area, frames go up to
50 instantly. Turning all speed-hacks on or using ZeroSPU2-plugin doesn't change anything.

Emulator:

-PCSXr4977
-GSdx 0.1.16 AVX (or SSE4.1)

-SPU-2Xr4949 V2.0.0 (interpolation=0, effects-processing=off,timestretch,
stereo)

- PAL BIOS V02.20 (10/02/06)
-native PS2-resolution

My system:

-Intel i3 2120 @ 3.3 GHZ
-Intel HD Graphics 2000
-4GB DDR-RAM
-Windows 7 64-bit

I read that the sound-plugin might cause the slow-downs so I switched
to Direct3D-sound and played around with latency ect, but doing so
either produced audio-bugs or did not do anything.

Any advice ?

have a nice day

that GPU won't help you, since it's very weak.
Else, are you on a laptop ?
if yes, set power plan to performance mode.

I'm on a desktop-computer. As I said, the EE-value goes down to around 50% which causes the slowdown. I know my GPU isn't that good, but the GPU-usage doesn't go up during slowdown. Locations slowdown occurs aren't even very demanding graphicallyIMO, e.g. boss battles are super smooth

if the EE% is @50%, it means you CPU isn't struggling.
WHat do the GS% say when you get those slowdowns ?

GS is always at ~30%, it rarely goes over 60. Even when slowdowns happen, GS remains at ~30 which is the same as when the game runs at 50 frames.

It seems neither CPU nor GPU are the problem as both aren't even close to being maxed out.

You'd have to try with a lower resolution than native, as jesalvein said it's a weak GPU and neither EE/GS% reaching 90-100% when you get the slowdowns indicate that would be the problem, some people play with a custom resolution of 384x384 but it's just ugly IMHO Tongue2

no, that's 256x256 384 isn't SO bad Tongue (I've tested 128 as well lol)

@ Shadow Lady

thanks for the advice. Switching from native to 384x384 erased the slowdowns. Game looks really blurry and bad, though, but at such a low res this shouldn't come as a surprise.


I should play around with the resolution a little to see what results I get with other games should they suddenly slow down. Or I'll simply accept the occasional dia-show (GOW1 ran at full speed 90% of the time).
