Valor Mortis PC requirements and launch-day PC issues

Four official steps, in order. Install the newest update first: the October 27 update reports more stutter and FPS improvements. Then update your GPU driver, which the developer names as one of the biggest helps for performance and stability.

If you played the Playtest or Demo, delete your old settings file, as the developer recommends: AppData\Local\ValorMortis\Saved\Config\Windows\GameUserSettings.ini. Delete only that file, not the Saved folder. Last, recreate your shader cache if stutter remains; the notice says PC players may need to and gives no path, so follow your GPU vendor’s instructions.

The developer says it is still investigating performance reports, so these steps may not clear every case. Kingy has not measured performance or tested these steps.

The developer reports further stutter mitigation and FPS improvements. PC players may need to recreate their shader cache, but the notice gives no deletion path or measured gain. Follow the game or GPU vendor’s instructions and preserve saves; do not infer that removing the Saved folder is required.

The outdated-driver popup is adjusted for handhelds that may already have the latest drivers. The patch does not explicitly resolve every RX 7000 fault listed below. Kingy has not measured performance or tested these fixes.

The update addresses common crashes and adds an outdated-GPU-driver notice. It does not explicitly close every RX 7000 issue or provide measured FPS gains.

For stutters after playing the demo/playtest, the developer recommends resetting AppData\Local\ValorMortis\Saved\Config\Windows\GameUserSettings.ini. Close the game and preserve a copy of that settings file first; do not delete the whole Saved folder. Kingy has not tested this remedy.

The October 21 patch fixes multiple crashes and slow-motion animations, and makes the outdated-driver pop-up clearer and less intrusive. On Steam Deck and SteamOS, the pop-up no longer asks you to update drivers you already have.

Neither patch note says the Radeon RX 7600 shutdown or RX 7900 XT crashes are fixed, so treat the AMD rows below as still open. Kingy has not measured performance on either patch.

Steam filled in the processor, graphics, Windows and target lines by launch day. Before launch the listing showed only 16 GB RAM, DirectX 12 and 50 GB, so older copies of this page and other sites may still show 50 GB with no SSD line. Plan for 60 GB on an SSD.

This is the developer's pinned known-issues list on the Steam forum. It names those two Radeon models as examples of the RX 7000 series problems; it does not say other RX 7000 cards are safe. No patch had been posted as of October 13.

Players report the game crashing at start-up or refusing to open again on launch day, some of them on AMD cards, in a shared Steam thread. No community fix has two agreeing reports yet, so none is listed here. Report a crash through the Steam Bugs and Issues forum or the publisher's support site, as the launch post asks.

The Xbox PC store minimum, checked October 10, matches Steam's minimum CPU, GPU and memory, and adds a Windows 10 build number and Hardware Feature Level 12. Neither listing is a benchmark: the frame-rate targets are the publisher's, with upscaling on.

A useful performance guide needs a named build, CPU, GPU, driver, settings and a repeatable test scene. Kingy has not run one.

The first three steps come from the store listing and the developer's known-issues post; the preset step is Kingy's suggestion, not a tested setting.

1. Free 60 GB on an SSD.
2. Update your AMD or NVIDIA graphics driver to the latest version.
3. If you have a Radeon RX 7600 or RX 7900 XT, read the known issues above before a long session.
4. Start from the Low or Medium preset that matches your hardware tier and adjust from there.
