Image Upscaling via FSR or NIS for SteamVR games v2.1.1

Hotfix: hotkeys could not be deactivated in the config file due to a missing conditional check.

Image Upscaling via FSR or NIS for SteamVR games v2.1

Changelog:

• add customizable hotkeys to adjust some of the mod's config parameters on the fly. For example, you can switch between FSR and NIS and also toggle debug mode on or off. Refer to the updated config file for available hotkeys and how to configure them.
• add possibility to take a screenshot of the final output image that gets sent to the headset. Screenshot is stored as a .dds file right next to the DLL. You can open them with e.g. Paint.Net.
• added some missing function exports in newer OpenVR versions. Might theoretically enable some additional games to run with the mod.

Image Upscaling via FSR or NIS for SteamVR games v2.0

This release adds NVIDIA's Image Scaling (NIS) as an alternative to AMD's FidelityFX SuperResolution (FSR). You can choose which algorithm you want to use by setting the new parameter useNIS in the config either to false (FSR, default) or true (NIS).

Both algorithms work similarly and take a similar amount of time, but the output is sufficiently different that it's worth experimenting which one you like better for a particular game.

FidelityFX SuperResolution for SteamVR games v1.3

Changelog:

• Properly handle submitted array textures. This fixes the issue with the latest Blade & Sorcery update.

FidelityFX SuperResolution for SteamVR games v1.2

Changelog:

• Fix color space issues when using the mod with Oculus store games via Revive.
• Take canted display angles into account when calculating the center of the FSR radius to improve stereo overlap on Pimax headsets.

FidelityFX SuperResolution for SteamVR games v1.1

Changelog:

• Fixed projection center for the radius application of FSR. The radius where FSR is applied should now give proper stereo overlap on all headsets.
• Added a debugMode option that, when enabled, visualizes the FSR radius and also periodically logs the GPU cost of the FSR application.
• Be a bit more conservative when overriding sampler LOD bias. Might (or might not) prevent some rendering issues when applyMipBias is enabled.

FidelityFX SuperResolution for SteamVR games v1.0

Changelog:

• fix incorrect color space in Dirt Rally 2, possibly others
• fix mod not being loaded in American/Euro Truck Simulator, possibly others (although there may still be some issues)

FidelityFX SuperResolution for SteamVR games RC2

Reverted a change in the internal texture formats that was supposed to preserve a little more color quality, but is apparently incompatible with several HMDs.

FidelityFX SuperResolution for SteamVR games RC1

Changelog:

• fix for IL2 and possibly other games
• apply a negative LOD bias for texture MIP levels, as per AMD's recommendations. Might result in a bit more texture detail, hard to tell the difference, honestly
• "fixed foveated" optimization: FSR is now only applied to a configurable radius from the image centre, any pixels outside the radius are upscaled by cheaper bilinear filter. Even with a fairly small radius, it is often hard to tell the difference due to the current HMD lenses. Feel free to experiment with it and gain a few additional usecs for your frametime budget :)

FSR for SteamVR games alpha 1.2

• Fixes for Assetto Corsa Competizione, possibly other games
• Properly react to changes in the game's render resolution
