Quantum Break Will Not Support Multi-GPUs

There's a bucket-load of issues with this game, here's a new one. Remedy has just released a new FAQ about the current state of its latest title, Quantum Break, there will be no Multi-GPU support. The company also has a problem with frame pacing, but does hope to solve that with an update. 

In May Microsoft will release a solve for the known vsync issues and also will/should solve GSync and FreeSync. Remedy also reports that the render technique used is similar on the XBox and Windows 10, meaning if you are playing at 1080p, the screen display is built from 720p buffers. So playing at any resolution really means you are watching at two-third of the pixels rendered (upscaling).

The PC release has been bugged by a bucket-load of issues related to ghosting, slow streaming of textures, frame-pacing, GSYNC/FreeSync, VSync locks and more. Some cannot be solved. Here's the FAQ released by Remedy (the makes of the game, the irony is in the name .. Remedy eh ?).

Windows 10 Issues & Solutions

Stuttering Frame-Rate / Frame Pacing
There was a major rounding error introduced into our refresh rate predictions on shipping. A solution to this issue is already being worked on; we expect it to be resolved in a Quantum Break Title Update launching in the near future.

Windows 10 Performance Issues
Remedy is looking into how to improve the overall performance of the game. Part of that is working closely with AMD and NVIDIA to address issues and improve the gameplay experience.

Sometimes, after a longer play session, the game can end up to a state where the video memory becomes fragmented, and an important asset gets moved to system memory, which slows the rendering performance significantly. This problem is very rare and Remedy will continue to investigate and improve the video memory behavior in future updates.

If you experience this issue, exiting and restarting Quantum Break will resolve this issue for now. This is one way to identify if you have encountered this issue or if it’s another potential problem.

Graphics Drivers:
We recommend, for AMD Radeon GPU’s, AMD Radeon Software Crimson Edition 16.4.1 and we recommend, for NVIDIA GPU’s, 362.00 from NVIDIA.

Keep in mind, these drivers might have an impact on other software on your computer.

Windows 10 Frame Rate Locked?
In May, Microsoft will be enabling the ability for developers to disable v-sync and adding support for G-Sync and Freesync monitors. This means that UWP games running in full screen, borderless windowed mode will have all of the performance advantages of traditional full screen exclusive mode.

No Option to Quit from Main Menu
We hear you! By popular demand, we are adding an exit option to the main menu in an upcoming title update. For now, similar to all Windows 10 apps, you will need to use Alt-F4 or move the mouse cursor to top right corner of the window to the see the X icon, which you can click to exit the game.

Crashing on Launch
We have been able to repro at least one reason for a rare crash on launch– with some SIMD instructions that require SSE4.1. We are working on fixing that in a future title update, and will fix any other issues we find as they are reported.

Image Quality
We are working on giving users more control to turn on and off features like film grain. We love the artistic choice for our game, but we also want to give PC gamers more choice and this will come in a future update.

Does Quantum Break support SLI or other multi-GPU solutions?
Quantum Break on Windows 10 unfortunately doesn’t support DirectX12 multi-GPU rendering. Due to the engine architecture, the work needed to support multiple GPUs would have been significant and out of scope for Remedy for Quantum Break.

Render technique and resolution on Windows 10
The Windows 10 version of Quantum Break uses the same reconstruction method as on Xbox One. If your resolution is set to 1080p, the game temporally reconstructs the image (except UI) from four 720p buffers rendered with 4xMSAA, just like on Xbox One. Engine assigns input geometry samples from 4xMSAA rendering into shaded clusters in order to maximize covered geometry while keeping the performance on acceptable level by reducing expensive shaded samples. When you change the resolution, the buffers used to construct the image are always 2/3rds of the set resolution, i.e. in 2560x1440 they would be 1706x960.
