Lossless Scaling frame gen on iRacing?

[price^G]

Has anybody tried it? Does it work? Couldn't find anywhere online and it'd help a lot to get more constant frames

Yes, I use it.

In rendererDX11Monitor.ini you can set them. (name can be different if you use VR)

CompressTexturesSuits=0
; 0=uncompressed 1=block compress (recommended)
CompressTexturesHelmets=0
; 0=uncompressed 1=block compress (recommended)
CompressTexturesCars=0
; 0=uncompressed (warning! no!!) 1=block compress (highly recommended)
CompressedVertices=0
; 0=off 1=Use compressed vertices

It can cause performance drops if you don't have enough Vram and GPU power. Especially the Cars one.

But if you have good specs, it shouldn't be a problem.

I have a RTX 3070 and usually get around 100-140 at 1080p (no FSR), so I doubt it uses all of its VRAM. I just want frame gen to make my FPS more stable.
Thank you!

Depending on the system it is possible you get better, or more stable frame-rates, because compression comes with issues itself.

I run constant 160 fps (triples @ 7680x1440) even on the big circuits with a lot of cars.

Thanks for that tip. But wasnt clear to me if you use LossLess software with Iracing, if you are showing how config in ini to use that software or just saying isnt necessary get that software? Thanks

You don't need additional software for losless. Just the settings in the .ini file mentioned above.

Sorry, you dont understood what we asking. Thanks anyway

Bit of necromancy, but I wouldn't use it, as any kind of frame generation, be it Nvidia Frame Gen, AMD's Fluid Motion Frames and Lossless scaling does increase latency.
And for good racing we need low latency, the whole point of high frame rates is to reduce the frametimes and with it the until displayed times so we can react faster.

Has been discussed for a while:
https://www.techspot.com/article/2546-dlss-3/
https://www.techspot.com/article/2747-amd-fsr-3-tech/

It's good for added smoothness in single player games that aren't dependant on reaction times:
-strategy games,
-Role Playing Games of the more classical and turn based kind.
-City Builders

, but a detriment in any game that demands fast reactions like:
-racing sims
-combat flight sims
-shooters
-Milsims
-rythm games
-action rpg
-fighting games. etc.

It also might not be a problem in a civilian flight sim if you play as an airliner, but the closer you get to the ground, like on landing, or when flying a helo, the more detrimental it gets.
You could argue that it isn't detrimental in train or truck sims, but pretty much only until a fast reaction is needed, like reacting to a signal.
(In the case of the German PZB, you need to have the acknowledge button down and then release it inside 2.5-4 seconds depending on type while you pass the Magnet with your loco's leading bogie. Now that magnet is less than a meter long, 68 cm, or 2 feet 2.77 inches, so hitting that right at 120 km/h or 90 mph is quite a reaction challenge.
Nevermin at 160 km/h or close to 100 mph. )
