In my case I aim for what settings are smoothest in the simulator without lossless scaling so for me that is 120Hz RR locked at 1/3 VSYNC so target of 40FPS {in game}. I then just use lossless scaling to boost that to 3x theoretical 120FPS. I rarely see 40FPS /120FPS but usually get in the region of 33/99FPS or at a very busy airport maybe 22/66FPS. I’m getting a much needed boost for new airports like EDDF in the Fenix.
i get artifacts on using 3 x or 4 x. Not when i am using 2x. Artifacts are mainly tearing of scenery through rotor movement. I wasnt able to use even 2x on my former 3070. Now i have 4070 super and no worries.
Yeah, most artifacts are when in external view and panning around or externally while panning around in the cockpit. Always external things though never cockpit instruments which are always very crisp for me. I don’t care though as it adds some much needed smoothness. This morning sat at the gate in EDDF with GSX and I was hitting 18FPS which is not great for setting up your aircraft, but lossless scaling made that a more manageable 54FPS which helped a lot. I don’t see much of a difference FPS wise using 2x or 3x get about the same pseudo FPS figure regardless. I’ve not seen a 4x option just 2 or 3x . (EDIT, just noticed 4X is there now so trying it out).
How does lossless scaling work on the 40xx series whith DLSS 3.0 FG? do you still need it?
What you’re doing doesn’t make any sense and you’re not getting any benefit from the software.
First, you’re not reaching the 40 FPS you’ve set as your target, so you’ll never reach 120 FPS (40x3). If you want to achieve 120 FPS, you must configure the simulator’s options to achieve that FPS rate, otherwise it will never work.
Second, don’t limit the FPS in the game and much less through the game’s Vsync. Use an external program, like Rivatuner and set the desired FPS, in your case 40.
Disable Vsync in the game completely and in LS use the Default option in the Vsync options.
Third, the program doesn’t generate pseudo FPS, it generates extra frames, just like Nvidia’s native FG does but by different methods. The biggest shortcoming is that LS doesn’t have access to motion vector data, which results in more artifacts during fast motion, and is especially noticeable at the edges of the image.
This is one of the reasons why Nvidia’s FG is better, but you need to have a 40-series card. If you have a 40-series card, it’s better to use Nvidia’s FG.
Artifacts occur at 2X (although, of course, they are exaggerated with higher multipliers).
They are clearly visible on some surfaces, through the moving propeller or in external views, when making fast camera turns.
If you have a 40-series card, it is better to use the native Nvidia FG. It will “only” double your FPS, but the method used is better and you will have better quality.
but directx 11 is allready using all of my 12 GB vram, and directx 12, which is beta, wont help in that case. i have got native 36 to 53 fps on TAA 4K, but if i fly heavies, KJFK with a320neo v2, my fps tanks to 18-20, thats on takeoff.
I mostly fly GA, so it doesnt matter, if i get little artifacts with lossless.
but that has nothing to do with it. VRAM is filled by models, textures, shaders. DX12 won’t help you, on the contrary, as it manages VRAM differently.
You should try to get at least 30 FPS by lowering some settings. Once you get there, use LS at 2x or 3x.
There is no remedy for artifacts, at least for now. You have to live with it.
I have an RTX 4090 and notice a bit of flickering (which drives me nuts, lol) on the TDS GTNXi when I move my head around with TrackIR. I don’t notice this Lossless Scaling. The only real downside I am seeing with Lossless Scaling is the terrible artifacting when panning around the outside. In the cockpit I really don’t notice this at all. Moving my head around with TrackIR on a 180Hz monitor is extremely smooth even though TrackIR is 120Hz.

worked incredibly well for me until recently, although frames read high its like a slideshow?
Anyone else experiencing this?
Using the latest driver works on my end. Did you by chance update to Windows 11 24H2? I heard that Lossless Scaling is broken in that.
yes, i did. My bad, went through iso.exe update process, so its irreversible
im still on windows 10 as of now.
I know this will sound weird, but I’ve been messing about with my settings again, and tried knocking my PC desktop down to a refresh rate of 60Hz, so I could try my previous sweet spot of 1/2 RR @ 30fps coupled with lossless scaling, and it was ok, but at dense airports like the new EDDF in the Fenix it’s still a bit of a push to reach 30fps. Well I ended up trying 60Hz desktop at 1/3 RR so targeting sim at 20fps (sounds low right?) but then adding in lossless scaling brings that up to a solid 60fps. The key for me here was that that 20/60 held steady for pretty much the whole flight and was very smooth including while landing at Ini’s EGLL (I did have clear skies tonight) with AI traffic (maybe the smoothest I’ve seen before here). The only dip in fps was while GSX was loading passengers. So although it sounds like somewhere you don’t want to go (low FPS), it seems to work nice and smoothly here for me. (3090 running @ 4K, TOLD 100, FSLTL traffic with IFR 50). So it maybe worth a try for some of you.

I just did another (resource heavy) flight using 1/3 VSYNC 60Hz target 20fps (in sim) + (3x) 60fps lossless scaling (LSFG 2.3) in the Fenix between Aerosoft EDDF and FlyTamps EHAM with AI traffic, and once again got a steady 20/60 the whole way including takeoff/landing. It’s very smooth on this setting, it may be a keeper for me for airliner use. Sure you occasionally get a few visual artifacts, but those steady and predictable 60 frames/sec are smooth with no stutters. Probably the best improvement I’ve seen in a while.

Since recently, I seem to get weird FPS-dips when rendering different addon airports… anyone else experience with this all of a sudden?
At what point of the process? Loading in? Gsx? Taxiing? Takeoff/landing?
Data cache on cache off?
There’s a lot of new pg around too for GE and UK.
Other than the usual stuff the only things that caused me notable performance slowdowns was cache filling up. Been that way since a couple of SUs ago. I turned my cache off because if this.
Hmm just loading up the flight at the gate, then engaging LS and it sinks to very low minimum/stutters. I messed a bit with my supersampling settings recently though as I got a new 4K monitor, maybe there’s an issue there that I hadnt before.
Doesn’t work on more than one monitor so not using it at the moment.
Were you running your card at 4K before getting the new 4K monitor. 4K does seem to be at the edge of limits for my 3090 to deal with especially with dense airports, AI traffic and the Fenix. Couple that with a couple of sim updates worth of general slowdowns, and I’m happy to have FG albeit just extra frame insertion rather than in between vector calculated frames.
I’ve always found best results in this sim when doing VSYNC and looking multiple fo refresh rate. So 120Hz/40FPS, 60Hz/30FPS, and now 60Hz/20FPS with Lossless Scaling.
Another flight today from EDDF to EGCC which was completely smooth from start to end on the 20/60 setting. It’s quite compelling when you start to see smoothness in this sim.
I have even been able to increase TLOD back to 150 and add back in slightly more AI traffic too.
Lossless Scaling is the best £5 I’ve spent in this sim in a long time.
Oh I run the sim pretty much on ultra nowadays (I won’t have clouds without, I made myself promise 
) I generally have 30 fps stable with only V-sync 1/2 engaged, where i engage LS I bump up to about 60 average. I use “that program with a puppy icon” 
to alter TLOD and OLOD settings, after passing 3000 feet AGL TLOD goes up from 70 to 300 and OLOD comes down from 200 to 20. I’ve got super smooth flight usually except when directly looking at some addon scenery once LS is engaged.
I think its a rendering issue as not all addon scenery has it and its not based on scenery size either. I suppose I’ll need to lower my texture synthesis setting maybe, go back to high from ultra and see if that did something.
