Their sample allows to run just the upscaler without sharpening, and guess what: for the most part the sharpening filter and their recommendation to render the scene with a lower texture mipmap bias are responsible for the crisper end result, not the upscaler itself. The second one is a sharpening filter that gets applied to the upscaled result. The first one is the actual scaler that upscales from the lowered render resolution to the higher target resolution. The method involves two shaders that are run after another. That’s what this actually is: upscaling + sharpening. But very similar results could be achieved with any other high quality upscaling method and some sharpening. I wouldn’t go so far to call this a full blown marketing stunt, it clearly has its value. This is nothing like nVidia’s DLSS and even that is really just good enough with the two higher quality presets. Just checked the sample app AMD offers for download and can’t say I’m super impressed. Hope that doesn’t sound too confusing.įor now that’s all theory though, we’ll see if and how things turn out. So instead of gaining performance, you gain image quality when turning on FidelityFX without changing the game resolution. you would run a game at 1920×1080 with vorpX + FidelityFX, the result would be comparable to running a ‘native’ FidelityFX game at 2560×1440.

With vorpX on the other hand the game would still be rendered at 1920×1080 and then upscaled to a higher resolution with FidelityFX before it is sent to the headset. That’s where the performance increase comes from, at the cost of reduced image quality compared to actually rendering at 1920×1080. when you set 1920×1080 in the game options, it might actually get rendered 1280×720, and then upscales to 1920×1080 using FidelityFX. That’s important to understand for comparing FidelityFX on/off.įidelityFX natively integrated into a game renders the game at a lower resolution, e.g. However: As always no promises.īe aware though that it would work differently compared to having FideltyFX natively in a game. *MIGHT* work, I’ll have experimenting with that on the list.
