FSR4 support?

[deennyy]

Hey, currently thinking of purchasing a 9070 series gpu, I was wondering if FSR4 is going to be supported in optiscaler, as not many games have fsr 3.1 (which is dll upgradeable to fsr4)

Edit by mod: Here's the link to the FSR4 Compatibility list with all necessary info.

I got a 9070 xt and would also like to know this :D fsr4 is so good

I don't think FSR4 has been open sourced yet. And maybe It will work with the driver-override when using FSR 3.1 output?

Devs are definitely taking a look at this and there is already work underway, but no promises since FSR4 is currently being kept as driver-sided.

Is there any possibility that FSR 4 will also run on RDNA3?

In its current form, don't count on it.

Hi,

Tonights nighly build is adding FSR4 support for RDNA4 cards. It's experimental so expect all kinds of issues. Also you will need to find amdxcffx64.dll in your Windows folder and copy it next to OptiScaler.

Seems to work at least in the one game I tried just now (KCD2 which was supposed to be whitelisted to begin with...), selecting FSR3.X shows FSR 4.0.0 as the active upscaler. Thanks for the quick work!

Tested with FF7 Rebirth and FSR4 seems to be working :D, image looks way better.

Using 9070XT

Hi,

Added a FSR4 Compatibility List to Wiki. Please share your experience there.

Done all the instructions but dont see the FSR4 applied when using FSR 3.X in deadlock

Looks like it's a Vulkan game. This might be the issue.

Unfortunately, crashes when selecting FSR 3.x in cyberpunk on 9070 XT

seems to be working in Hellblade 2 w/ 9070XT w/ OptiFG and hudfix

EDIT: crashed after about an hour of gameplay. unsure if related to this but probably. driver failure it seemed
EDIT2: played another hour, no issues. seemed to be a driver issue possibly on the first crash. might've been caused by mod, not sure, but also they are fairly new drivers on the AMD side

I'm getting a crash as soon as I select FSR 3.x in cyberpunk on 9070 XT.

FFVII Rebirth seems to be working. At 100% resolution scale I don't immidiately see any issues. At 66% or lower there's a ton of fizzle on trees.

I have FSR4 working in Cyberpunk with both the XeSS and FSR3 options in settings, selecting DLSS causes a crash. Can't remember if I manually edited the ini last night when I first tried though, might've crashed during the toggle.
