Identify which feature is missing
DLSS Super Resolution, DLSS Frame Generation and Multi Frame Generation are separate capabilities. An unavailable frame-generation option does not necessarily mean Super Resolution is broken.
NVIDIA’s Borderlands 4 launch documentation lists DLSS Super Resolution for GeForce RTX cards, DLSS Frame Generation for RTX 40-series, and Multi Frame Generation for RTX 50-series. Use the feature your GPU supports rather than a hand-written list of individual model numbers.
1. Use the actual upscaling menu
Open Options → Visuals → Advanced → Resolution Scaling. Under Upscaling Method, select DLSS if it is offered for your setup. The same section contains quality and frame-generation controls. The official performance guide suggests trying Performance quality and Frame Generation On, but image quality and responsiveness still need comparison on your display.
If DLSS is missing on an AMD or Intel GPU, choose an available alternative such as FSR, TSR or XeSS instead of trying to install NVIDIA files.
2. Update the driver and check the detected GPU
Install a current supported driver through NVIDIA’s official driver tools. Reboot if required. On a hybrid laptop, confirm the game is using the intended RTX GPU in Windows graphics preferences.
Record the GPU and driver version. A screenshot of the actual Resolution Scaling section is more useful than saying only “DLSS is broken.” If Super Resolution works but frame generation remains unavailable, include that distinction in the report.
3. Restore the stock game installation
If the issue started after a mod, injector or DLL replacement, return to the stock setup using that tool’s uninstall instructions. Then verify files through Steam’s Installed Files page or Epic’s Manage → Verify action.
Do not use a guessed DLL size, an assumed plugin directory, or a downloaded replacement binary as proof that the installation is correct. Launcher verification is the supported first check.
4. If frame generation is unavailable
Check the GPU generation above, then follow the official PC guide’s Windows HAGS instructions for your system. Change one setting, reboot when requested, and test again. This page does not impose an unsupported 60 Hz monitor requirement or guarantee that one Reflex/VSync combination unlocks a disabled option.
For a supported GPU that still lacks the control, capture the menu and file a support report with the Windows version, driver and game version.
5. If it works but looks or feels worse
Compare the same scene with frame generation Off, then On, without changing the upscaling quality. Watch fine detail, movement and input feel as well as the displayed FPS. Then compare the quality presets separately.
If reducing render resolution barely changes performance, the workload may be limited elsewhere. Use the low-FPS comparison routine rather than assuming the DLSS file is corrupt. After graphics changes, allow shaders to settle before comparing results.
FAQ
Can RTX 30-series use DLSS? NVIDIA lists Super Resolution for all GeForce RTX gamers in its BL4 documentation. That is separate from RTX 40-series Frame Generation and RTX 50-series Multi Frame Generation.
Should I rename the DLSS DLL? File verification and a current driver are the first steps here. Manual binary replacement adds another variable and is not required by this checklist.
Does the site guarantee a percentage FPS gain? No. NVIDIA’s published performance figures describe its own test setup. They are not a benchmark of your PC.
GPU feature source
NVIDIA’s BL4 DLSS and Reflex documentation distinguishes the three DLSS capabilities. Check the dated source and your actual menu together.
Source and reporting a remaining problem
This checklist follows the official PC troubleshooting guide, checked October 18, 2026. It is a diagnostic sequence, not a promise that one step fixes every PC. Record your CPU, GPU, driver, resolution, game version, exact error and the result of each test. Send those details with DxDiag and MSinfo to Borderlands Support if the problem remains.
