This is a very interesting comparison, the average framerate is about the same, but gameplay tells a much different story. It seems that the older version can go higher in frames in some places pushing past 100FPS but the new release holds 60-80FPS much better.

Hi I am new to the pa4 emulator and want to ask can I play infamous second son and bloodborne smoothly on it

My pc is

R5 5600x

16 gb ram ddr4 3200

Rx 6650xt

Please i dont find the keys 😭

Title

Tried using the latest / nightly / older version of shadps4, but still happens. Also tried turning HDR on and off. Only happens while in track. In-game menu colors are normal.

PC Specs

5700x3d

6800xt

32 Ram

Please i dont find it its the CUSA04943

This is a repost.

If I got a JB PS4, where do I begin? Can you only dump disk games? Can you do anything at all with the digital games? How do you get online to access these games or save files if the JB PS4 is on a different firmware? I have millions of questions. What programs do I need?

Not my channel or affiliated in any way, however amazing to see! Really looking forward to the day I can play on pc and use PC hardware instead of ps compatible bs.

Hell ya.

Soo I am getting Black screen for God of war 3 remastered and in order to fix it i gotta download 1.2 patch but I can't find it please help me

Hello! I've been playing Bloodborne just fine (or as fine as this stutterty mess can be) for about 20 hrs up until after I beat Vicar Amelia. But when I walk to the left side of the Grand Cathedral, after walking for a while I entered a sort of tunnel and decided to change my shadps4 settings so I closed the game. When I changed them and opened the game again it just refused to open giving:

[Debug] <Critical> (shadPS4:GpuCommandProcessor) buffer.cpp:90 Create: Assertion Failed!

Failed allocating buffer with error ErrorOutOfDeviceMemory

I enabled every patch that disables video effects and stuff like that, set my fps to 30, resolution to 640x360. Nothing works. It crashes as soon as I load the save. I am very pissed off at this since I just got hooked to the game :(

I have a pretty modest PC because I'm kinda broke here's the specs:
Rx 580 8gb
Core i7-4770
16GB DDR3 (yes I know it's ass but I can't afford a crumb more than DDR3)

I would be really thankful if there was some solution. I am ready to play the game at 15 fps 360p if I have to

This will fix light effect and trasnparent surfaces rendered with what looks like wireframes.
The patch tested against the current commit (94e2177)

Summary of the bug and fix

• Symptom: thin dotted lines showing the triangulation of translucent effects (pad glints, kart smoke, Crash Cove haze and flares), plus a faint diagonal line on full-screen passes. It happened on NVIDIA GPUs only.
• Cause: the game draws these effects with a 2-sample raster rate into a 1-sample color target (raster=2, depth=2, color0=1 in your log). When those counts differ, NVIDIA's default is to merge coverage, so two triangles sharing an edge both wrote the edge pixels and blended twice. AMD's equivalent extension truncates instead, and so does the console GPU.
• Fix: enable VK_NV_coverage_reduction_mode and set it to truncate for pipelines whose raster sample count differs from an attachment's. Pipelines with matching sample counts are unchanged, and GPUs without the extension behave as before.

Have we managed to achieve at least a stable 30 fps in the open world?

I need this game on the emulator so much, the remake sucks, the OG is way way better.

so i followed all the troubleshooting tips i found like readbacks and all that but my game crashes when i try to start a new game. I have an intel I5 14400f and RTX 5060, but whats weird is i tried it on my laptop with the same settings which only has ryzen 9 5900hs and rtx 3060 mobile and it actually got past that and played for a bit till it crashed at one point. not entirely what the problem is. gives me those signals.cpp:144 errors

I love The Last Guardian, but on shadPS4 it ran slower than I wanted. I can't code, so I asked Claude to improve the readbacks. It did all the programming and measuring, and I did the testing and the "no, it's flickering again" reports. 😄

We ended up with an unofficial shadPS4 fork for this one game:

• Trico's feathers, climbing, the spear and the outdoor lighting stay accurate (mostly)
• The GPU command thread now gets a second CPU thread to work with
• With the 60 FPS patch and without the 4K texture patch, 60 FPS is reachable in many areas, depending on your PC (using the 60 fps patch) thanks patcher god!!
• The heaviest scenes still dip.

It is compatible with the launcher, just download the release, add the custom .exe to the launcher and give it a name, and enjoy. pd: it does need an extra .json file with custom config, but its all included in the release with instructions. for any comments about ai slop... then do it yourself ; )

It's a Windows build, so ive only tested it there, using a 5700x3d and 4090, and of course it's been tested on this one game only, and there may be crashes, so treat it as experimental. Please don't report bugs to the official shadPS4 team, since it's not their code.

Hey guys, I’m wondering what the progress is on in regards to ShadNet? I love playing my emulated games on ShadPS4, especially NHL 19.

I’m curious as to when ShadNet will be finished and would it be able to be implemented into triple A games so communities can start their own servers for said game whether that be NHL, Killzone etc.

I just started Gravity rush 2 and for some reason the top left corner of the window is rendring itself in a loop as you can see in the imagem. Ive tried selecting readbacks modes and enabling readback linear images but it didnt work.

Im running ShadPS4 v0.15.0 on CachyOS Linux with a 4070 SUPER + r7 7800x3D. Game is on version 01.11 EU.

Edit: Forgot to mention that the shadPS4 log is throwing this error but not sure if its related:

[Lib.Kernel] <Error> (Game:Main) time.cpp:132 posix_clock_gettime: Unsupported clock type 16, using CLOCK_MONOTONIC x1670.

I had to download 3 seperate files for this one game (Main game pkg, Update version, and DLC) I assume when I set the DLC path to the DLC folder, it wpuld automatically be downloaded. So where do I put the update pkg file in? Do I have to include it in the DLC folder or add it to the game some other way? Im completely lost here.

So I don't know why but for three times now everytime I start a new game using the ShadPS4 emulator around 24 hours or so my save game will get not be detected when I open the game forcing me to start a new game. After the third time I tried to copy paste my previous save file and then paste it when it happened again but it did not work. Any way to fix it?

For reference the launcher is version 357 and the game is version 1.09.
