Best Doom Eternal settings for the NVIDIA GTX 1660 (2026)
On a NVIDIA GTX 1660 (paired with a balanced Intel Core i5-8600K-class CPU), Doom Eternal runs at roughly 64 FPS at 1080p with our optimized settings — up from about 64FPS with everything maxed. Here's the configuration and what each setting costs.
The NVIDIA GTX 1660 is a entry-level graphics card with 6GB of VRAM, and Doom Eternal is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 64 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.
Across resolutions you can expect around 64 FPS at 1080p and 61 FPS at 1440p, dropping to roughly 46 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

|---|---|---|
| 1080p | 64 | 64 |
| 1440p | 39 | 61 |
