RDR2 OptiScaler Frame Gen Guide: Easy FPS Boost for RTX GPUs

Product Reviewed

OptiScaler mod / DLSS Frame Generation DLL (NVNGX_G) is used to enable “multi frame generation” in Red Dead Redemption 2, with the goal of unlocking higher FPS on NVIDIA RTX GPUs.

Key Features Mentioned

• Uses NVIDIA’s official DLSS frame generation DLL: NVNGX_G (via the OptiScaler mod).
• Supports multi frame generation multipliers, including 3x, 4x, and 6x.
• Includes a HUDFIX option intended to reduce HUD flickering.
• Provides a mod menu with pre-configured input/output settings; the user mainly needs to activate.
• Includes a “Dynamic Frame Gen” option and an FPS limit slider to stabilize/hitch frame generation on first enable.

Pros (User Experience / Benefits)

• Gameplay feels mostly smooth, even at 6x multi frame generation.
• Mouse response is described as surprisingly well by the reviewer.
• HUD flickering can be mostly reduced by enabling HUDFIX, making the game “completely playable.”
• No original game files are replaced (installation is done via drag-and-drop), which the reviewer calls a massive advantage:
  • Replacing fewer/no base files helps avoid instability/crashes seen in older approaches.
• A setup tweak—Dynamic Frame Gen plus temporarily raising the FPS limit to 200—can make frame generation “skyrocket” and run properly after initial instability.

Cons (Issues / Limitations)

• HUD flickering artifacts are a major issue on RTX 20 and RTX 30 series GPUs, attributed to a hardware/architecture mismatch:
  • RTX 40 and newer RTX 50 series reportedly do not experience the flickering.
  • HUDFIX does not eliminate flickering 100% on RTX 20/30; the reviewer still notices some ammo counter flicker.
• Character glitching during fast mouse movements occurs more with higher multi-frame multipliers, especially on RTX 20/30.
  • The reviewer states there are currently no settings that fully or significantly fix it.
• Shadow flickering, especially while riding a horse at high speed.
• Higher multipliers (e.g., 6x) increase visible artifacts compared to lower ones.

Recommended Settings / Comparisons

• Best balance recommendation: 3x multiplier
  • The reviewer says 3x or 4x offers the best tradeoff between smoothness and visual quality.
  • 6x is usable but comes with more visible graphical artifacts.
• GPU comparison:
  • RTX 40 / RTX 50: no HUD flickering issue mentioned.
  • RTX 20 / RTX 30: HUD flickering persists (partially mitigated by HUDFIX) plus other artifacting behavior (glitches/shadows).

Setup / Installation Notes (as described)

Installation

• Download, extract with WinRAR/7zip, then drag & drop into the main RDR2 folder (where RDR2.exe is located).

Settings before enabling

• Scale method: DLSS Quality or Balanced
• Graphics API: DirectX 12
• Motion blur: off
• V-Sync: off

In-game enabling

• Press Insert to open the OptiScaler menu → click activate.

If unstable / hitching initially

• Enable Dynamic frame gen
• Raise FPS limit slider to 200
• After a few seconds:
  • Disable Dynamic frame gen
  • Reset FPS limit slider to 0

HUD mitigation

• Turn on HUDFIX:
  • Improves flicker, but doesn’t fully remove flickering on RTX 20/30.

Numerical / Explicit Claims

• Achieved: “6x multi frame generation”
• Stabilization step: set FPS limit to 200, then reset to 0
• Suggested multipliers: 3x, 4x, 6x
• No formal rating score was provided.

Unique Points Mentioned (Consolidated)

• Unlocking 6x multi frame generation in RDR2 on RTX 30 series
• Mostly smooth gameplay at high multipliers
• Mouse response remains surprisingly good
• HUD flickering occurs due to using DLSS frame generation on unsupported RTX 20/30 architectures
• RTX 40/50 avoids HUD flicker entirely
• HUDFIX reduces flicker but doesn’t fully eliminate it (ammo counter flicker remains)
• Character glitching during fast mouse movement at high multipliers on RTX 20/30
• No current settings meaningfully fix character glitching
• Shadow flickering while riding at high speed
• Preference for 3x/4x over 6x for fewer artifacts
• Installation does not replace original game files, improving stability
• Specific installation method: drop extracted files into the RDR2 main directory
• Recommended graphics settings: DLSS Quality/Balanced, DirectX 12, motion blur off, V-Sync off
• Use Insert to open the menu; click activate
• Stabilization trick: enable Dynamic frame gen, set FPS limit to 200, then disable/reset
• Enable HUDFIX for playability

Speaker / Role Breakdown

• Single speaker; no separate perspectives were clearly indicated.

Overall Verdict / Recommendation

Recommended only if you prioritize FPS smoothness and can tolerate visual artifacts—especially on RTX 20/30. The mod works best with 3x (or 4x) for a better balance. On RTX 40/50, the reviewer implies the experience is significantly cleaner due to no HUD flickering.
