Experimental! But very significant improvement! I bet boost mode on PS4 pro would smooth out the left over slowdown in areas.

@Stayhye did u ever try GTA LCS?
 
Fix for Shadow Hearts Covenant NTSC

More testing needed, but got past title screen but after few FMV black screen again:disturbed:

Fixes frame rate issues by skipping bloom effect. May need additional settings to work properly.

Game still suffers from slowdown and stutter.

"--vu1-di-bits=0" fixed most of the stutter but game still has severe slowdown. Scalars don't seem to help...

Can't do anything more to help then. This patch fixes the slowdown on PS3 and PCSX2 but PS4 must have something else going on in addition.

Could you take a look at GTA:LCS?

Sorry, I already took a look and it's unfixable on my end. I tried disabling a lot of stuff, like the overlay effect and fog, but it brought no performance boost. I would guess lowering the draw distance might help with the performance, but I wasn't able to find it. The game is playable on PS3 to an extent (it was released as an official classic) since it has frame rate issues that don't affect the game speed, yet the game struggles most of the time with it.

Do you know how the Hot Shots Golf games perform on PS4? There's a fix for those games by disabling shadows that will probably apply to PS4.
 
Not bad. I used the configs for Hot Shot tennis and that fixed most things. I've seen your fixes for PCSX2, I just haven't tested them on PS4 yet..

Anyone have any ideas for Blood Omen 2? The game crashes emu after ps2 logo. NTSC and PAL same result...

I found a weird one....Genji Dawn of the Samurai. This one will freeze randomly during FMV and title screen. Never makes it to gameplay. Tried many emu versions, no dice. Any Ideas?

The SCES53328 version works with the "GTA 3 v1" that you sent me choosing 50hz, in 60hz the game crashes.

Figures. Been beating my head on the NTSC version since 2020 lol

*Edit- After testing, thanks to hint from @Bortoloti , PAL version works perfectly with emu GTA 3 v1. No CLI needed. NTSC version will sometimes make it in game, but controller doesn't respond after a while, OR game freezes before game play during FMV. ??


Summoner NTSC works perfectly with the primal emu

apiRequest(0.1)

local eeObj = getEEObject()

local patcher = function()

--ISO patched due to crashing when code put here

end

emuObj.AddVsyncHook(patcher)

emuObj.SetGsTitleFix( "forceSimpleFetch", "reserved", { texMode=1 } )

Game now allows for 2x2 upscale. Only issue is the game seems to not uprender? Works perfectly otherwise......

More testing needed but seems to work fine.
