Last week there was news about a new version Lossless Scaling, which allows you to enable Frame Generation in all PC games on any video card – for a modest fee. Recently, the developer provided the publication DSOG code for testing and the guys tested its capabilities in different games and shared their impressions.
As noted, Lossless Scaling Frame Generation has some limitations. The program needs the game to be locked to half the monitor’s refresh rate. So if you have a 120Hz monitor, you’ll have to cap games at 60fps. With other settings, problems arise with displaying frames. Luckily, this is easy to do through the Nvidia Control Panel. Additionally, LSFG is not compatible with VRR-enabled monitors.
The publication notes that owners of monitors with G-Sync/FreeSync will have to completely disable G-Sync in the control panel. With G-Sync enabled, the LG CX and LG 32GK850G-B monitors experienced serious frame rendering issues. This happened even when setting the refresh rate to 120Hz and capping the game’s frame rate at 60fps. The only way to solve this problem is to switch to “fixed refresh rate” mode. After this, Lossless Scaling Frame Generation worked as it should.
Another point that has been made is how BAD 60fps looks on a monitor without VRR support. With G-Sync enabled, 60fps felt smooth on both the LG CX and the LG 32GK850G-B. Even when rotating the camera in Elden Ring or Cities: Skylines 2, 60Hz looked great. However, when set to “fixed refresh rate”, 60 frames per second no longer seemed so smooth. While close objects moved smoothly, distant objects looked a little jerky.
Here’s a quick summary for each game:
-
Cities: Skylines 2: FPS drops, problems with ghosting overlays and icons, smoother gameplay
-
Elden Ring: Issues with ghost images, issues with frame rendering and stuttering, slight lag when moving mouse
-
Chernobylite: minor ghosting issues, smoother gameplay, minor stuttering
-
Kingdom Come Deliverance: Issues with ghost images, smoother gameplay, slight stuttering
-
The Medium: best example, here LSFG works fine
-
Assetto Corsa Competizione: severe FPS drops, ghosting and frame rendering issues, game felt bad
The bottom line is that while LSFG has underwhelmed in most modern PC games, it can significantly improve older games that are locked at 30fps. Or you can use LSFG to improve the performance of emulated console games running at 30 FPS.
For everyone else, LSFG is a controversial pleasure. Yes, LSFG can improve your gaming experience if you are still gaming on a non-VRR monitor and your graphics card can support 60fps in games. In this particular case, Lossless Scaling Frame Generation will improve the smoothness of games. However, if you have a G-Sync monitor, LSFG is definitely not recommended. And LSFG doesn’t even come close to the quality of DLSS 3. DLSS 3 Frame Generation doesn’t have as many ghosting and input lag issues as LSFG.
Additionally, DLSS 3 works perfectly with VRR technology. Also, with DLSS 3 FG you can get better performance, which is not possible with LSFG – since even small drops below 60 frames per second can cause problems with frame timing.
