Thanks for all this info and testing! These are good numbers to see! However, I wanted to take a second to correct something I believe might be inaccurate in your understanding, specifically, a bit of a misunderstanding of what exactly it is that Anti-Aliasing is doing for the render. In short, it's not related to the shadows at all, which you mentioned and gestured to a few times when talking about it. In regards to games, it's almost exclusively going to be related to the edges of the objects themselves to help them appear smooth. Which is to say, this does not tie into the cast shadows or shadow maps. It COULD have a small effect on how they're perceived as the filter is applied, but in iRacings case, as I'll explain a little of below, the shadow resolution is low/bad enough that you're not going to really see much happening there, you'll primarily see it on the edges of objects on a very small, only a few pixels like 1-3, level whereas those shadows are extending across 20px-100px depending on resolution. In my case for example, if my AA is below 4x, I can see the edges of curbs where they connect to the road in particular as well as handrails etc. show kind of a "shimmer" as I move along the track. This happens because the edges get kind of a stair step effect with out AA, especially on lower resolution. So though it's expensive, I pay the cost because I hate that shimmer. The value of AA is also resolution dependent, so for higher res screens it might be much less necessary than lower res screens. Additionally, when changing between FXAA and SMAA, if you already have AA off, I'm not entirely sure that there will be any effect, specifically because AA is already off, so there's no processes happening in either case. Can't remember if you had AA on or at 2/4/etc or not when messing with that setting. A more thorough explanation can be found here - kzbin.info/www/bejne/nJnRnqpqbK1jkKc In regards to the Jaggies on shadows in iRacing, I'm not entirely sure the specifics here, but I believe this is a short coming of their engine and the rendering tech. A great example you can probably see, if you take a flat colored car into the paint room, and just start moving around, you'll essentially see stripes across surfaces. This gets a bit into tech I'm not entirely familiar with, but what I believe is happening there is essentially the lighting having an iteration over distance, which is would KIND of work like a resolution in its own way. In some cases, you can see this type of visual can be found due to low resolution shadow maps, however, shadow maps are not used on dynamic shadows as we'd see on the cars and such. To say a little about that, cast shadows are still pretty expensive when it comes to creating a render, but you can see how far we have come in more modern games when we have settings/tech that allow an objects shadow to blur the farther away it gets from its source, vs iRacing's striped artifacts. jagged edges and lightly blury edges, causeit's a much older title, obviously. But, all that to say, I believe that's an artifact of iRacing's lighting specifically, but at the very least, it is not tied to AA when it comes to shadows. Hope all that's of some value, thanks again for taking the time to put all this together for folks!

Shadow resolution defines the crispness of shadows, not the AA value. In iRacing, that's the StaticShadowRes and the DynamicShadowRes lines in the .ini file. Set DynamicShadowRes=4 for cockpit textures with no bluriness..

I put the MMSA samples to zero for sports track racing and it was horrible, the lines on the side of the road become pixelated and triangled and it appeared to be rendering as I drove, causing the corners to be unclear. It was hard to judge the corners and apexes. I changed them back to x4 quick smart. It may not affect oval racing as much, as you do not need to concentrate on braking for corners. Also be aware that if you change the compressing, iracing will reset you screen parameters, viewing distance and also your iracing graphics setting to default and you will have to put them in again, so it may be good to take note of what they are before you change it. Would have been good if you mentioned this in the vid, as it took a lot of troubleshooting for me to correct again. In the end, I just resorted to my original settings and was down about an hour of my time from messing around. I really should have just left it how it was in the first place with the setting from your last video a year ago, that video helped me more for mu situation. This video was not an improvement for my PC. The old saying, if its not broken, dont try and fix it. haha

iRacing has it's own shadow resolution setting in the .ini file which could be why you don't see much change there when you mess with the AA settings. I do see a fairly noticeable difference in the turn 1 wall jaggedness when you go from a higher AA number to 0, although even with higher AA it's still pretty ugly. Guess it just depends on if you think that small improvement is worth it for the performance hit.

You put a lot of work into this, but that is one massive misunderstanding of what MSAA does. MSAA is sub-pixel sampling that improves the jaggedness of high contrast transitions in the image, it has nothing to do with shadows. The reason performance changes two fold from 8x to 4x is because the GPU is by definition doing almost half the work in rendering the image. 8x is still not a reasonable setting to be on, but 4x or 2x are absolutely a good choice especially if you are on a 1080p or 1440p display. You might not have noticed any change going from 8x to 0x since you had SMAA enabled in the other anti-aliasing section.
@1nfinitum2 ай бұрын
You are also misunderstanding the concept of bottlenecking. Graphics rendering has almost nothing to do with the CPU, you're not bottlenecking your CPU by running your graphics card harder. Your graphics card will do all the work that you throw at it until there is no more work to do; this means that if you set your graphics to low in iRacing, your GPU will continue to render frames well past the refresh rate of your monitor. This isn't inherently bad, but it is extra work that the GPU is doing that it doesn't need to be. That's what the FPS limiter and VSync settings are for in iRacing. They help you throttle the performance of your graphics card to prevent it from constantly overworking to render frames when it's not necessary. You absolutely can be bottlenecked by your CPU, but I guarantee that is not the case with a 13900K unless you're trying to hit a frame rate target of 240. A better term for what you are experiencing is having your frame rate be CPU limited. In other words, your frame rate will not go any higher because your CPU is working at 100% calculating the engine, physics, and all other iracing subsystems while the GPU sits idle because it has to wait for the CPU to be done before it can render the next frame to screen. There is no mysterious performance loss when using low graphical settings with a high end graphics card, if anything you're prolonging the life of your card by spinning the fan less and heat cycling the GPU die less excessively, but that is generally not a very strong concern.

@@1nfinitum Exactly, most sim titles whether thats racing or flight has a lot of calculations behind it due to all the phyisics needed to be calculated which is all done on a cpu. Going above 150fps or so is very difficult for most sims due to the cpu. Also talking about his custom loop and how much he has overclocked it I can pretty much say that will gain you 5-10 fps at an extreme end which is also when everything is optimised for those speeds too, sometimes an overclock is steady but is slower than standard depending on how stable it is. Setting low/off MSAA shows a massive difference, it goes from very ugly to only slightly ugly. I do have mine set to 8x as I really do notice a difference, or at least I did as I haven't tried it for a while.

iRacing uses 2 different settings. If you are actually in the car driving then it's using graphic settings. If you're just watching then it's using replay settings.

It's good this way as some want better graphics for photo/video and broadcasting while not caring about getting above 60fps like they would if they were actually racing.

Interesting stuff - strange that iRsidekick seems to very much disagree with the compressed textures "Since 2023 Q4 iRacing is using a lot of VRAM on new tracks, it is essential to compress all textures to avoid blurry graphics" Gonna give it a try anyway :)
@ZoneXV2 ай бұрын
Don't bother trying to prove the iRsidekick guy wrong, aka Martin Lanza. Dude has a seriously complex where he can't be wrong. He thinks just because iRacing allocates a certain amount of VRAM if you let it, that is how much it needs. That is why even though iRacing might allocate 8GB of VRAM if you let it, you can limit it to 6gb with the same scenario and not run into blurry textures. I went through and did A/B testing, showing how much VRAM was utilized, and how little difference the compression made with the numbers and he still acted like he was right. If you have a GPU with 10GB or more VRAM you should ALWAYS have compression turned off, with 8GB I still would turn it off. The biggest difference I could get in VRAM usage between compressed vs uncompressed was 700mb. Even with that, iRacing does a pretty good job of swapping in mip levels for textures at shorter and closer distances.
