NVIDIA Reflex 2 still absent from games, while modder publishes its own Frame Warp test for free

Apparently it works on RTX 20+ GPUs.

One of the features announced alongside the GeForce RTX 50 series was DLSS 4 with Multi Frame Generation and Reflex 2. The latter never shipped enabled in a real game, despite traces and tech demos shown in The Finals. It is hard to judge the technology when there has been no public demo for 10 months.

Meanwhile, Modder PureDark has now released a free demo that showcases Reflex 2’s Frame Warp. He says the demo exists because new Reflex 2 related files were found in recent game builds. Similar files were present in The Finals, but went unnoticed.

In the last video, I mentioned that I reverse engineered the nvngx_ratewarp.dll leaked in the public testing of ARC Raiders
But later it was discovered that this file was already included in The Finals in May, but it has not been enabled yet
If I had discovered earlier, Reflex 2 could have been tested in May
Note: According to Nvidia, Reflex 2 is only supported on 50 series at launch, but it seems even RTX 20 can run this demo.

Reflex 2 with Frame Warp takes fresh mouse input while a frame is rendering and reprojects the camera right before display output. The goal is lower perceived input latency, including when Multi Frame Generation is enabled.

Tom’s Hardware tested the demo on an RTX 5070 Ti. Using Nvidia’s FrameView, PC Latency measured around 7.8 ms at 240 FPS with Frame Warp off. With Frame Warp on, the readout dropped to roughly 1 to 2 ms at the same 240 FPS. That is an approximate 81% reduction on that system. The outlet cautions that FrameView may not yet report Reflex 2 latency perfectly, so treat the numbers as early data.

Image artifacts are visible. The demo shows some distortion near screen edges with Frame Warp enabled. These artifacts are less distracting above 120 FPS, but they remain at lower frame rates such as 90 FPS. The demo also runs on older GPUs like the RTX 2080 Ti, though edge artifacts are worse there.

Despite being announced at CES with promised integrations for The Finals and Valorant, Reflex 2 with Frame Warp still appears as “coming soon” for GeForce RTX 50 series. Nvidia has not rolled it out in shipping games yet. PureDark’s demo does not change that status, but it shows how the feature could behave once officially released.
