DOOM Eternal Best Settings for RX 6600 at 1440p

Banner for the DOOM Eternal PC settings guide

DOOM Eternal is a rare case for a settings guide: an RX 6600 at 1440p is not fighting to run it — it runs with headroom to spare. That flips the usual question. Instead of "what can I afford?", you get to ask "where do I want the surplus?" This guide covers the small number of options worth touching at this tier: the quality presets, the texture pool that spends VRAM rather than frames, the temporal anti-aliasing that gives the game its slightly soft look, and how a game this fast changes what a good frame rate means.

Who This Preset Is For

  • RX 6600 (8 GB) playing at 2560×1440.
  • Players who want a crisp, high frame-rate arena shooter, not a screenshot simulator.
  • Anyone unsure whether the higher quality tiers or Nightmare textures actually cost anything.
  • People who notice the image looks a touch soft in motion and want to know why.

The Honest Situation: You Have Surplus Frames

DOOM Eternal's engine is famously efficient, and 1440p on an RX 6600 sits in its comfort zone. In practice that means the top quality presets are within reach, and most options move the frame rate by small, predictable amounts rather than cliffs. The two exceptions worth knowing about:

  • Texture pool size is a memory decision, not a frame-rate one — it decides how much of the card's 8 GB the game may fill. At 1440p the higher tiers are usually fine; the symptom of being wrong is not a lower frame counter but occasional hitches as memory churns.
  • Anti-aliasing (TSSAA) is temporal — it borrows information from previous frames to smooth edges, which is why the image can look softly blended in fast motion. Some players love it, some sharpen around it. Both are valid tastes.

Recommended Settings

SettingRecommendedWhy (subjective)
Quality PresetHigh (Ultra is within reach, taste call)High and Ultra are close visually; High leaves clean headroom for a high frame-rate target. Try both, keep what you cannot unsee.
Texture Pool SizeHigh-ish tierSets the VRAM budget. 8 GB at 1440p usually holds the upper tiers; if long sessions hitch, step this down first. See our texture guide.
Texture Filtering16x / maxNearly free on this card and noticeably sharpens the floor at grazing angles in arenas. See our filtering explainer.
Anti-Aliasing (TSSAA)On, quality tier HighFast motion makes aliasing obvious; TSSAA handles it at the cost of slight softness. Off only if you prefer shimmer to softness. See our AA comparison.
Shadow QualityHighArena readability benefits from grounded shadows, and the cost is modest at this tier.
VRS (Variable Rate Shading)On, if offeredAn engine-level efficiency feature. In our view it is free headroom with barely visible trade-offs in a game this fast.
Upscaling (FSR, where offered)OffYou do not need it at this tier — upscaling in a game you already run at high frame rates spends image quality for nothing.
Frame Rate LimitYour monitor's refresh (or a bit below)A game this fast rewards a stable cap over an uncapped bouncing counter. See our VSync guide.
FOV100–110Default is tight for how quickly demons flank. Widen until the edges stop feeling like blinkers. See our FOV guide.

Judging the Result Properly

Do not calibrate in the first room. Judge the preset in a late-game pitched arena — the wide battles with dozens of demons, explosions and a marauder or two. That is where both the frame rate and the readability questions get answered. Second test: the platforming stretches, where the game's speed makes any softness or shimmer easiest to notice.

  • Frame rate is part of the game here. In most titles a dip is cosmetic; in an arena shooter a 144-locked rhythm is gameplay. Spend the surplus on consistency, not on marginal texture tiers.
  • Softness in motion is TSSAA. If it bothers you, do not gut other options chasing sharpness — compare the AA quality tiers and filtering first.
  • Hitches are a memory conversation. A steady counter that occasionally hitches points at the texture pool tier, not at shadows.

Quick Tips (In-Game Options Only)

  • Set your frame cap first; every other decision is easier once the target is honest.
  • Widen FOV before judging image quality — the tight default makes fast play feel worse than the graphics deserve.
  • A/B the quality preset tiers in one saved arena: if you cannot name the difference at full speed, take the cheaper one.
  • Texture filtering to max is the best "free sharpness" option on this card.

FAQ

Can an RX 6600 run DOOM Eternal at 1440p?

Yes, with large headroom on high quality settings. This is one of the best-optimized shooters on PC; the guide is mostly about where to spend the surplus frames, not how to survive.

Should I use the Nightmare-quality options?

Taste call. The top tiers look great, but the visible gap from High in full-speed combat is small for some players. Test in a busy arena at real speed and keep whichever you can actually perceive.

Is the soft look fixable with settings?

Largely, yes: it comes from the temporal anti-aliasing. Max texture filtering, the higher AA quality tier and the in-game sharpening option (where offered) firm the image up without touching anything expensive.
