Black vertical lines covering the image in higher internal resolutions (Tekken Tag Tournament, Tekken 4 & 5) #138

In both Tekken Tag Tournament, Tekken 4 & 5 (some of the only games I've been testing so far in RetroArch using this libretro core) using build 4244ddd of the pcsx2 libretro core I've encountered some visual oddities like black vertical lines surrounding the image in gameplay. I'm using the bios scph39001.bin, and the only thing I've changed from the default values in the core options of pcsx2 is the internal resolution (3x 1080p instead of native because I prefer higher screen res).

I haven't encountered this issue in some of the other games I've tried with this libretro core, such as Burnout 3, Lemmings, Katamari Damacy & We Love Katamari.

I'm using RetroArch 1.9.8 in Windows 10 64 bit, GeForce GTX 1080, i7-4790K, 32gb DDR3 ram and I use gl as Video Output in RetroArch. I haven't encountered those issues running the pcsx2 emulator itself while playing those games.

Below is an image of this issue when playing Tekken Tag Tournament.

Have you tried enabling Quick Menu > Options > Hack: Align Sprite? I remember that fixed it for me in Tekken 5, I don't have TT and 4 to test tho.

That was the first thing I tried, but that didn't change anything with the black vertical lines. I tried again, and then restarted the emulator with Align Sprite Enabled for every Tekken game. Now it works flawlessly. All in all, user error, I'll close this issue now.

For Tekken Tag, you can also set 'Interlacing Mode' to 'No interlacing Patch' and it should also take care of this without having to enable 'Align Sprite', while giving you a much crisper image.

Thanks, even though I read the news entry on libretro.com regarding this I didn't catch that detail. I thought that the default interlace mode on auto-mode did the trick of loading those no-interlace patches automatically now, but there was the issue.

Funny though that my i7-4790K from 2014 isn't fast enough for Tekken Tag Tournament 1 on PS2 with 3x native resolution (framedrops).

Edit: When going to bed last night I read through the latest libretro.com news entry slowly, and now I managed to run Tekken Tag Tournament way smoother by having a core override of RetroArch in pcsx2 where the Video Driver is dx11 and so is the preferred rendering API for Tekken Tag Tournament 1. The gameplay was slow at first (maybe some pre-caching of shaders), but it ran buttery smooth after a while.
