Here is how to fix shimmering and achieve the best image quality while playing Grounded 2 with Lossless Scaling on RTX 40 Series GPUs.

Grounded 2 is a sequel to the original Grounded game and is currently in Early Access. That said, the game’s settings options are presently minimal, offering only customizable levels: low, medium, high, and epic. Since it’s a UE 5 game, it currently has a lot of performance issues. GPUs like the RTX 4070 Ti and the 4070 Ti Super struggle to play this game at Epic settings at 1440p with 100% resolution scaling.
That said, below is a comprehensive article on the entire RTX 40 series line of cards, and how, with the help of Lossless Scaling, you can get around those annoying shimmering and low framerates.
Note: Use Windowed mode explicitly to ensure Lossless Scaling works at its best. The higher your monitor’s base resolution, the better the results will be. For example, if your desktop resolution is 1080p, setting a window resolution to 1336×768 or 1600×900 will yield the best results. Likewise, if your desktop resolution is 1440p, then set the game resolution to 1920 x 1080. For 4K, set your desktop resolution to 2560 x 1440. As the pattern suggests, we are going for a quality upscaling methodology.
Grounded 2 – Best Settings for GPUs Upto RTX 4070 Ti Super

The game doesn’t support DLSS or DLSS FG as of yet. If you do not have lossless scaling, then you can use these settings at your native desktop resolution. Next, drop the resolution slider to 70%, which uses TSR to upscale the game, but this results in a significant loss in image quality.
Setting | Value |
Window Mode | Windowed |
Resolution | Native Resolution – (Your Monitor’s Resolution) Render Resolution – (75% or 66% of your Monitor’s Resolution) |
Render Scale | 100 (Lower this as per visual tolerance, if you do not have Lossless Scaling) |
Quality | Medium (4070 TI Series) Low (4060 – 4070) |
Frame Rate Limit | Unlimited |
Depth of Field Blur | Low |
V-Sync | Off |
Gamma | 38% (Preference) |
Motion Blur | 0% |
Chromatic Aberration | Off |
Field of View | 110 (Preference) |
Grounded 2 – Best Settings for RTX 4080 Super Till RTX 4090

With the RTX 4080 Super and the RTX 4090, relying on upscaling isn’t mandatory, unless you are on 4K resolution and want to play the game at a super high framerate. But if you desire that super high frame rate, using lossless scaling seems to be the only way to do so now, particularly with frame generation.
Setting | Value |
Window Mode | Windowed |
Resolution | Native Resolution – (Your Monitor’s Resolution) Render Resolution – (75% or 66% of your Monitor’s Resolution) |
Render Scale | 100 (Lower this as per visual tolerance, if you do not have Lossless Scaling) |
Quality | High |
Frame Rate Limit | Unlimited |
Depth of Field Blur | Low |
V-Sync | Off |
Gamma | 38% (Preference) |
Motion Blur | 0% |
Chromatic Aberration | Off |
Field of View | 110 (Preference) |
Lossless Scaling Settings

You can ignore this section if you do not own this software. Also, consider G-Sync, HDR, and Capture API; you’ll need to experiment and find out what suits you best. For instance, our game experienced gamma issues when selecting the capture API as DXGI.
Setting Category | Option | Value/Selection |
Frame Generation | Type | LSFG 3.1 |
Mode | Adaptive | |
Target | 143 (A bit below your monitor’s refresh rate, value is for reference) | |
Flow scale | Keep at the default | |
Performance | Off | |
Scaling | Type | FSR |
Sharpness | (Preference) | |
Optimized version | On | |
Mode | Auto | |
Display Mode | Fullscreen | |
Capture | Capture API | WGC (You may need to change this to DXGI) |
Queue target | 1 | |
Cursor | Clip cursor | On |
Adjust cursor speed | Off | |
Hide cursor | Off | |
Scale cursor | Off | |
Crop Input | Crop Input | 0 |
Rendering | Sync mode | Default |
Max frame latency | 3 | |
HDR support | On (Situational) | |
G-Sync support | Off (Situational) | |
Draw FPS | On | |
GPU & Display | Preferred GPU | Auto |
Output display | Auto |
Verdict
This concludes the recommendation for Grounded 2 for the entire RTX 40 Series lineup. The GPUs mentioned here range from the RTX 4060 to the RTX 4090, including the Super.
