NVIDIA has recently released DLSS 3 technology with a new feature called Frame Generation, which is only supposed to be available on their latest GeForce RTX 40 series graphics cards. However, a Redditor has figured out a way to activate the feature on an older RTX 20 series card.
DLSS 3 Lock Bypassed? Redditor Enables Frame Generation on GeForce RTX 2070 With A Simple Config File
A Reddit user named JusDax shared in the NVIDIA subreddit that they have discovered a way to enable the AI-Assisted frame generation feature, DLSS 3, on older RTX 20 series graphics cards. This feature is set to be included in Cyberpunk 2077 and is known to greatly improve the frame rate.
The Reddit user JusDax has claimed that they were able to bypass the DLSS 3 lock on older NVIDIA GeForce RTX graphics cards by adding a config file to remove the VRAM overhead in Cyberpunk 2077. They ran the game at 1440p with HDR off and DLSS set to balanced mode, and were able to select the Frame Generation tab under the Ultra ray tracing preset. According to JusDax, this resulted in a performance increase of around 2x, going from 35-40 FPS to 80 FPS. However, JusDax also experienced some instability and frame drops while using this method, and it is not clear whether the lock on DLSS 3 is due to hardware limitations or a lack of software optimization for older GPUs. JusDax has not shared any images or the config file, so it is not possible to verify these claims or test the feature for oneself.

Re: NVIDIA DLSS 3 Lock Bypassed on RTX 2070
I had suspected, once again, it was nothing more than a marketing ploy. DLSS does not enhance response time. Hence, if you were under the impression that your inputs would be processed with increased speed, such as in a racing game where it is essential, you shall be met with disappointment. Absolutely nothing is achieved, as only a few intermediate frames are displayed, and your control input remains unchanged. Indeed, even more lamentable, due to the heightened CPU load, your control input will even be processed with decreased velocity. Therefore, it is not suitable for racing purposes.
