An XDA Developers contributor says they used the community tool OptiScaler to enable NVIDIA Multi Frame Generation on an RTX 4070 Ti, a feature officially limited to RTX 50-series cards. In a test of The Blood of Dawnwalker, the contributor reported higher displayed frame rates at 3x and 4x generation, alongside lower base frame rates and increased VRAM use. This is a community workaround, not official NVIDIA support, and the figures are from one system and game.
The contributor describes OptiScaler as a tool that lets users experiment with upscaling and frame-generation implementations in games that support DLSS or FSR upscaling. According to the account, OptiScaler alters architecture checks in NVIDIA’s frame-generation software as it loads, making the RTX 4070 Ti appear to meet the Blackwell GPU requirement. The report does not establish that NVIDIA endorses or supports this workaround.
In the cited test, the contributor used an RTX 4070 Ti, Ryzen 5 7600X and 32GB of DDR5 memory to run The Blood of Dawnwalker at 2160p with High settings. The reported average was 43 fps with DLAA, 64 fps with DLSS Quality, and 96 fps with DLSS Quality plus 2x frame generation. With OptiScaler enabling 3x and 4x generation, the contributor reported displayed averages of 138 fps and 160 fps, respectively.
The same table shows why those figures need context. At 4x generation, the reported base frame rate was 40 fps, compared with 69 fps for the 2x result; VRAM use rose to 11.6GB out of the stated 11.7GB maximum. The article presents these as results from its particular test setup. It does not provide multi-game testing or establish how the workaround performs across different systems and titles.

Average displayed frame rate
Scale: 0–160 fps3× generation
138 fps displayed
Reported base rate: 44 fps. Generated frames raise the displayed count; they are not all newly rendered by the GPU.

Reported base rate: 40 fps, with 11.6 GB of 11.7 GB VRAM in use.
Read the result carefully. Displayed frame rate is not the same as native rendering performance. The report includes no latency measurements, and higher displayed rates do not prove a similar gain in responsiveness.

Measure in context
Compare displayed and base rates, plus VRAM, latency, quality, and stability.
The account also mentions Control Resonant, but provides no comparable benchmark table for that game.
What remains unknown
Compatibility and performance are still unclear
A single-game result cannot establish how the workaround behaves across the wider game library.
Support status
Does NVIDIA officially support MFG on RTX 4070 Ti?
No. The source says official Multi Frame Generation support is limited to RTX 50-series cards. This result used OptiScaler.
Meaning of 160 fps
Did the GPU render 160 frames each second?
No. The reported 160 fps is a displayed average with generated frames. The reported base rate was 40 fps.
General compatibility
Will the workaround work in every game?
The source does not establish that. It gives detailed figures for one game and mentions another without a matching benchmark table.
Next useful evidence
What would clarify the results?
Repeatable tests across games and hardware, with base and displayed rates, latency, image quality, VRAM use, and stability.
A Software Workaround, Not Official Support
The report matters to owners of RTX 40-series cards because it describes a way to try a feature that NVIDIA has restricted to newer hardware, without replacing the GPU. It also shows how a software check can shape access to features when related processing hardware may exist on an older card. That does not show that every RTX 40-series GPU can run MFG reliably or deliver the same results.
Frame generation creates additional displayed frames; it does not make the game render the same number of new frames from scratch. In the reported test, the 4x mode’s 160 fps average accompanied a 40 fps base rate. Readers should not treat the generated-frame figure as equivalent to native rendering performance, nor infer that higher displayed rates necessarily mean a similar improvement in responsiveness. The source does not provide latency measurements.
For people considering a GPU purchase, the distinction is practical: OptiScaler may offer an experimental alternative, but it is not a substitute for official support. The method involves modifying software behavior, and the article’s single-game data cannot establish stability, image quality or compatibility across the wider game library.

From DLSS 4 to RTX 50 MFG
NVIDIA introduced Multi Frame Generation with its RTX 50 series, with the feature described in the source as generating up to six frames. The article says MFG requires native game support and remains officially exclusive to RTX 50-series cards; it also says NVIDIA has not announced plans to bring it to older GPUs.
The contributor places the workaround alongside other software updates and community projects they say extended the usefulness of their RTX 4070 Ti, including newer DLSS models and Smooth Motion. They describe the card’s original frame-generation capability as 2x and say MFG was the remaining feature they wanted to try. These are the writer’s account of their own hardware and software experience, not a general claim that all older cards gain the same capabilities.
According to the technical explanation in the source, NVIDIA’s newer frame-generation model relies on AI Tensor cores rather than the earlier Optical Flow Accelerator approach, and RTX 40-series cards also have Tensor cores. The account says OptiScaler patches checks that identify Blackwell architecture in the frame-generation module. The source does not independently verify every technical detail or provide the tool’s full installation procedure.

Compatibility and Performance Still Unclear
The published figures do not establish how well OptiScaler’s MFG workaround works across other games, driver versions, RTX 40-series models or PC configurations. The account gives detailed results for The Blood of Dawnwalker and mentions Control Resonant, but does not provide a comparable benchmark table for the latter.
It is also unclear from the source how the workaround affects input latency, image artifacts, crashes or long-term stability. The reported VRAM use approaches the stated maximum in the 4x test, but the article does not report whether that caused stuttering or other problems. The contributor’s findings should be treated as one user’s test, not as a guarantee of results.
NVIDIA has not announced official MFG support for RTX 40-series cards, according to the source. The report does not say whether NVIDIA has commented on OptiScaler’s approach or whether future software updates could change its compatibility.

Further Testing Would Clarify Results
The next useful evidence would be repeatable testing across more games and hardware, including reported base frame rates, generated-frame rates, latency, image quality and stability. Such tests could help distinguish a high displayed frame-rate reading from a consistent improvement in playability.
For now, RTX 4070 Ti owners should view the method as an unofficial experiment, not a supported NVIDIA feature or a proven reason to keep or replace a GPU. The source provides no announced NVIDIA update or formal compatibility roadmap for MFG on RTX 40-series cards.

Key Questions
Does NVIDIA officially support Multi Frame Generation on the RTX 4070 Ti?
No. The source says NVIDIA limits official MFG support to RTX 50-series cards. The RTX 4070 Ti result was achieved through the community tool OptiScaler.
What frame rates did the RTX 4070 Ti test report?
In The Blood of Dawnwalker at 2160p with High settings, the contributor reported averages of 138 fps at 3x generation and 160 fps at 4x generation. The corresponding reported base rates were 44 fps and 40 fps.
Does 4x frame generation mean the GPU renders 160 frames each second?
No. The reported 160 fps is the displayed average with generated frames. The test table lists a 40 fps base rate for that setting, so the figures are not equivalent to 160 natively rendered frames per second.
Will OptiScaler’s workaround work in every game?
The source does not establish that. It reports testing in two games and gives detailed figures for one; broader compatibility and stability remain unclear.
