How did you launched it? I got only 1 file whitout extension and Xenia can't launch it.

[BotanKun11]

This one is a mix bag. I mean my friend can't get it to boot with his AMD card & Xenia would crash for me on Xbox Live Arcade Logo or Product Identification screen & even hang Windows. I just did open file > (Bunch of letters & numbers) of Perfect Dark XBLA file

[sheppard66]

Ok thx for the answer, I have an AMD card so I understand why it doesn't work

Now booting to gameplay as of benvanik/xenia@27c16b19362a11cd92de9f034477afd5156e577c in GL.

Here's some gameplay on benvanik/xenia@d586574. If u have AMD card, u most likely run into black screens at main menu. Thanks for info gibbed

On the recent version the game runs smoother but the video is distorted and most of it goes black.

Using Nvidia 1060 6GB

Recent changes to Vulkan have dramatically improved the game. Now runs at full speed with minor movement glitches (Joanna seems to randomly sink to the floor before popping back up) and graphics equivalent to GL.

You should change status to playable. Xenia from 3/4/18 plays it on my AMD radeon 7700 almost like on real HW (except when i select combat simulator,coop or counterop, it does not do anything, but i know what it could be. It’s most likely that dialog, which is used in all local multiplayer games to log in other controllers. Xenia outputs, the dialog was cancelled)
With older xenia (1.0.1219 texsplit i was getting major graphics bugs with glass, and invisible enemies)
I can look at how xenia emulates those dialogs

When i choose Combat Simulator in main menu, it shows loading... and then goes back to main menu.

Playable from start to finish but has noise on models.

I've been following progress here for a while, but I'm still seeing a significant issue with an nvidia card. Apart from the noise on models, my framerate tanks the more of the game I play. It starts out fine, but frequently hits single digits if I restart a mission, or spend too much time in one.

I haven't really seen anyone report this, but it makes the game basically unplayable for me.

I've tried using Vulkan and D3D12, but Vulkan gives me a black screen.

If it helps, I've attached my config file:
xenia.config.toml.zip

Not a bug but the game is unplayable with headless=true because first option in XBOX LIVE connect dialog does nothing

[Triang3l]

On Nvidia, vertex varying interpolation is inexact, for vertices with exactly -1 texcoords, some pixels get -0.999…, while the pixel shader expects exactly -1 (has a == comparison with -1), so we're getting that noise on models.

[Timecrash]

Update for me: I don't know if it was a Xenia update or a config change I made, but I no longer get slowdown. Perfect Dark is now perfectly (ha) playable apart from the noise on models.

I've reattached my latest config; I made a couple changes to get DoDonPachi working.
xenia.config.toml.zip

@Triang3l Is this something that can be fixed with a config change, or will it require a new build?

[Triang3l]

@Timecrash It's a hardware bug, or rather, imperfection (it's still apparently within the precision requirements of the D3D12 spec) in Nvidia hardware. I currently don't know how it can be fixed (apart from manually interpolating with SV_Barycentrics, but that requires a huge shader translator rework, and is not guaranteed to help).
