LRPS2 replacing PCSX2

Nope. Nvidia card (with Nvidia driver obviously). The only two unusual things graphic card/driver related I noticed on my system is that the d3d11 and d3d12 drivers stopped working at some point for me while they worked before (if I try to set the gfx driver to either d3d11 or d3d12 it just crashes RA before even loading any content) starting at 1.11.0 though that was a long time ago. Might be related to this issue:

Glcore and Vulkan works well with one caveat regarding Vulkan is that with N64 cores using the parallel RDP it crashes for me. A few other users at least have reported the issue. As mentioned in that thread, might be gfx driver/card related.

In both cases it appears the issue only affect very few users/systems so understandably it’s harder to debug. Not sure if those issues are related to this problem.

If anyone else has Windows 8 installed please let me know in the thread whether you’re able to load the core or not.

Well, my rig is relatively old, GTX 960 + i5 6400, but as I mentioned, with d3d11 standalone pcsx2 runs quite well @1080p.

great core, congratulations! it works perfectly for me on linux by setting vulkan or glcore as video driver (with gl it doesn’t work) and using these ps2 bios:

$ ls ~/.config/retroarch/system/pcsx2/bios/
'Sony PlayStation 2 BIOS (E)(v2.0)(2004-06-14)[SCPH70008].bin'
'Sony PlayStation 2 BIOS (E)(v2.0)(2004-06-14)[SCPH70008].mec'
'Sony PlayStation 2 BIOS (E)(v2.0)(2004-06-14)[SCPH70008].nvm'

i used an intel iGPU (HD Graphics 630). For me vulkan runs as fast as opengl with LRPS2. To slow for some games but many ran just fine - for example NTSC Versions of god of war and silent hill 2 both run nearly flawless with both drivers. I use latest lakka 5.x GBM Image and imported the LRPS2 core nightly some days ago. Sadly for Parallel Renderer the intel igpu is WAAAYYY too weak for good speeds, but it works at least!

Yes, that’s been my experience with intel 630, as well.

I found works okay with glcore but has Graphic Issues that at least 6-7 Yeara Old with Graphics Card

That with my Main PC that is Older but Tried new Gaming PC that made in the 1-2 years and seem to work very well with Nivida Graphics card

Try Way of the Samauri but when talking to someone they all like they got Beards

Tried NFL Head Coach and found in Coach Now selection that only a bit of head is showing

Hi, I noticed that the video quality of retroarch+LRPS2 is slightly lower than PCSX2 standalone even though you are using the same settings.

Maybe I need to set some other options?

#35

I think the difference is made by the option “Bilinear upscaling: Bilinear (Sharp)” of pcsx2. Unfortunately on the retroarch core this option is not there :disappointed_relieved:

RetroArch itself have a bilinear filtering option under Settings > Video > Scaling > Bilinear Filtering . Maybe that’s why this option was omitted from the core itself? This option is recommended to set off if you have any Shaders in effect too.

thanks, I have activated Bilinear Filtering in retroarch video settings and now the video quality of PS2 games is identical to pcsx2 stand-alone!

How are you guys adjusting your shader settings for this core? When I bring up the F1 menu, I have a black screen and I can’t see adjustments that I’m making. Is there a trick to it?

Aside from that… I wanted to say that I’ve been playing it for a couple days and it is very rock solid. Compared to where it was at just a few months ago when we first saw it, it has made some really great progress. The retroarch guys have done a really awesome job on this core. Thanks, guys. :+1:

What i need to know is, am i the only person who has noticed frame pacing issues with PAL games in this new core? So far nobody else has confirmed this.

The old core supported VRR and the 50fps PAL games were smooth. This one doesn’t.

#41

things like framerate issues are often very subtile, and PAL and VRR is not that common i guess.

Why not just output 50 Hz as the original Hardware would do?

#42

Because i don’t want to manually change the refresh rate of my monitor every time i want to play these games. There isn’t a 50hz option either way.

It’s the VRR’s job to keep games run smoothly and in every other core it works, except this one. Plus, the old PS2 core was also working fine, which makes it feel like a regression to my eyes.

It would be enough for me if someone else acknowledge/confirm the issue. Because if there’s only one person having this then it will never get fixed.

Sadly my system does not support vrr. Otherwise i would Look for it

#44

I was going to check into it and then realized I don’t have a single PAL PS2 game.

Having some problems with Tomb Raider Anniversary. It’s like this in game as well. Changing the video renderer doesn’t fix it, software rendrer activly crashes the core. Only the Tomb Raider games are affected so far. I’m on a 7000 series AMD GPU with internal graphic.

[edit] Why is the default for memcard saves the System folder and not the Saves folder?
