AAA Titles

Cyberpunk 2077

Settings	FPS	Notes
1080p High + FSR, no RT	70–90	elektricM docs
1080p High + FSR + RT (lighting only)	50–60	elektricM docs
1080p Ultra + FSR3.1	100+	elektricM docs
1080p CPU-bound areas	<60 even at lowest (Discord user)	CPU bottleneck in dense areas
Power draw	Up to 235W	Most demanding game in the library (elektricM docs)

Benchmark scores:

• Stock (2000 MHz, 1000 mV): 57.66 FPS — elektricM docs
• OC (2230 MHz, 1035 mV): 60.82 FPS — elektricM docs
• With mitigations=off: +18 FPS boost — elektricM docs
• 38 CU, 2270 MHz GPU, 4050 MHz CPU, 1975 MT Memory, Ultra no FSR: min FPS >60 — dznuts (May 2026). Matched RTX 3060 performance level. Memory OC gave +18.4% min FPS boost.

Tips: Enable FSR Quality for a significant boost. DLSS/FSR Frame Generation works well. (elektricM docs)

Black Myth: Wukong

Settings	FPS	Notes
40 CU, 1080p Low (FSR off)	61 avg	Old Lamer YouTube benchmark (June 2026)
RX 6700 (reference)	59 avg	Same test conditions for comparison
RX 7600 (reference)	71 avg	Same test conditions for comparison

Source: Old Lamer YouTube benchmark (40CU BC-250 vs RX6700 & RX7600). The BC-250 at 40 CU slightly edges the RX 6700 in this title. See 11-community-and-resources for link.

Hogwarts Legacy

Settings	FPS	Notes
1080p Medium	~60 (Discord user)	Needs zram enabled (16 GB RAM is tight)
With FSR4 on Proton GE	Playable [confirmed: @lonewolf05849, 16/01/2026]

Game needs ~16.5 GB RAM. Enable zram: zram-size = ram x 0.75 and close background apps. [confirmed: @hojnikb, 08/03/2026] Use 6 GB static VRAM allocation to avoid OOM crashes. [confirmed: @big_trov, 28/02/2026]

Red Dead Redemption 2

Settings	FPS	Notes
Full graphics (DX11)	Smooth (45+ FPS min — elektricM docs)	Heatsink barely warm with 120mm fan
2230 MHz GPU	Crashes (Discord user)	Reduce to 2150 MHz for stability (Discord user)
10/6 VRAM split	Fixed crash (Discord user)	Static allocation avoids ZRAM conflicts

Launch flag: -useMaximumSettings — elektricM docs Adapter fix: May detect as software rendering — change adapter in graphics settings to match vulkaninfo --summary output (elektricM docs) Temps: ~75C during gameplay. [confirmed: @.strykur, 15/01/2026]

Spider-Man 2

Settings	FPS	Notes
Medium, 6 GB VRAM	~60	GPU/CPU around 65C
1080p native AA, Medium	55–60	Textures Medium, rest Low
1440p FSR3 Quality	~55–60	Similar to 1080p native
Auto VRAM	Crashes after 5–10 min	Must use 6 GB+ static allocation

Fix: Add kernel params: ttm.pages_limit=3959290 ttm.page_pool_size=3959290

---

Elden Ring

Settings	FPS	Notes
Any settings	45–51 (Discord user)	CPU-bound — elektricM docs report expected 60 FPS with settings adjustments
4K	30–40	Playable but choppy

Changing resolution/settings may not help. Fix skybox artifacts: RADV_DEBUG=nohiz in Steam launch options.

The Crew Motorfest

Settings	FPS	Notes
1080p High	60 capped	GPU OC 2100 MHz, CachyOS with Proton-Cachy

Borderlands 3 [Discord user]

Settings	FPS	Notes
1080p Medium, 8x AA	~62	Eden-6 benchmark; inventory has black box background (cosmetic only)

Starfield [Discord user]

Settings	FPS	Notes
1080p Medium	48–60	60 FPS capped with frame gen
1080p High	39–60	FG: 58–60 FPS
1080p Ultra	35–60	FG: 58–60 FPS, temps 64C max
1080p Medium (New Atlantis)	48–53	Most demanding location

Starfield is surprisingly playable with frame gen. Medium or High preset with FG gives a smooth 60 FPS experience. GPU OC 1000–2220 MHz, P12 Pro fan.

Alan Wake 2

Settings	FPS	Notes
1080p	~100 with FG	Reported playable, frame gen recommended

Shooters & Action

Doom Eternal

Settings	FPS	Notes
Ultra (not max VRAM)	100	Loves Vulkan
512 MB VRAM	Heavy stuttering	Needs higher VRAM allocation

Doom: The Dark Ages (Update 2+)

Settings	FPS	Notes
Low / Handheld preset, 1080p, FSR Quality	~60	GPU 2230 MHz, CPU stock

Fix: VRS crash — use Vulkan_NullVRS layer (bangstk, May 2026).

Crimson Desert

Settings	FPS	Notes
1080p Medium, no scaling	38–42

Fix: Use Proton Experimental Bleeding-Edge branch with VKD3D RDNA1 fix. Version 1.02 works. [confirmed: @nohanmv, 01/04/2026]

Death Stranding 2

Settings	FPS	Notes
36 CU, ultrawide 1440p High + frame gen	60 locked	dartzon, CachyOS, Thermalright PA120, GPU backplate cooler, <72C

PICO upscaler: PlayStation's FSR equivalent was ported to PC as "PICO" — works on Decima engine games (Horizon, Death Stranding). User reports it's superior to AMD FSR3 (dartzon, May 2026).

Cooling: dartzon used Thermalright Peerless Assassin 120 + GPU backplate cooler with fans for VRAM chips. Temps never exceeded 72C with 36 CU unlocked.

Monster Hunter Wilds

Settings	FPS	Notes

Performance Optimization Tips

1. 1080p is the sweet spot — 1440p works with FSR, 4K only for older titles (elektricM docs)
2. CPU is the main bottleneck in most modern games (GDDR6 shared memory latency) [confirmed: @corbanitevevo, 08/12/2025]
3. VRAM: 4 GB for most games, 6 GB for demanding AAA titles (elektricM docs: 4 GB recommended; 6 GB from community)
4. Use FSR for free performance boost (elektricM docs)
5. Update to Mesa 26.x+ for best compatibility and performance (elektricM docs)
6. Try Proton-GE for better compatibility (elektricM docs)
7. Kernel 6.19.x for VRR and DP audio fixes (gennro); 6.18 LTS as stable fallback
8. Mesa 26.x recommended — significant RT and performance improvements; 25.1+ minimum
9. mitigations=off gives ~10–15% FPS boost in CPU-bound games (elektricM docs: "mitigations=off for +10-15% FPS")
10. Keep GPU under 85C for long-term stability (elektricM docs)
11. Disable Handheld Daemon if using Bazzite for gaming (elektricM docs):

    sudo systemctl disable --now hhd && sudo systemctl mask hhd

12. CachyOS may be ~5–10% faster than Bazzite in raw benchmarks [confirmed: @.captainwasabi, 23/05/2026]
13. 40 CU unlock: more CUs at lower clocks match higher clocks at stock 24 CU — cooler and less power (big_trov: 40 CU at 1200 MHz = 60 FPS at 73C, 30W less than 24 CU at 2000 MHz achieving same FPS). See 02-BIOS.

40 CU Extreme already surpasses the 24 CU record (4713) by 22%+ at lower clocks (2300 vs 2530 MHz). Theoretically should reach ~6500+ at equivalent clocks. More scores expected as community adopts the unlock. Post your results in the Discord #benchmarks channel.

Max clock findings: 2400 MHz at 40 CU causes hard OCP lockup requiring power cable pull (reset/power buttons unresponsive) across multiple boards (big_trov, codyrainy, cralant). 2100-2300 MHz is the stable range for most boards. Trimming CUs for higher clocks is not advantageous: big_trov's 32CU @ 2400 MHz scored worse than 40CU @ 2300 MHz, with similar power draw (~270W).

38 CU voltage findings (May 2026): 38 CU at 2200 MHz requires ~1050-1060 mV (dznuts). 1085 mV not enough for 2230 MHz with 38 CU. At 2200 MHz, 995 mV is stable for some boards (codyrainy). Power limit and voltage ceiling intersect at ~2200 MHz for most boards, creating a hard stability ceiling.

Memory OC (May 2026): dznuts tested memory OC at 1975 MHz CL26 using RobinMemTiming. Only +80 points in Superposition and +1 FPS in Cyberpunk — not worth the instability risk. Memory OC causes 1-in-20 boot failures (no POST).

Efficiency insight (big_trov): More CUs at lower clocks match the performance of fewer CUs at higher clocks, at lower temperature and power. 40 CU @ 1200 MHz = 60 FPS (73C, 30W less than 24 CU @ 2000 MHz achieving same FPS). OCP hard lockup (big_trov, codyrainy, cralant): 2400 MHz at 40 CU causes hard lockup where reset and power buttons do nothing -- requires pulling power cable. Likely Over Current Protection triggering. Consistent across multiple boards regardless of cooling. One user with AIO reported 2400 MHz stable at 1120 mV. CPU OC affects GPU stability (big_trov, hojnikb): Increasing CPU from 3500 to 4000 MHz lowered the GPU voltage threshold for hard lockup. Total system power draw matters -- undervolt CPU when pushing GPU limits. Game-specific instability (May 2026): RE4 Remake crashes even with stable stress tests. Games need more voltage on GPU than synthetic benchmarks to be stable. If benchmarks pass but games crash, increase voltage by 10-15 mV. Voltage wall at 40 CU (big_trov, May 2026): Two limit curves govern 40 CU stability -- a voltage ceiling and a power limit. These curves intersect at approximately 2200 MHz, creating a hard stability ceiling. Above this point, diminishing returns are severe regardless of cooling. Power consumption: ~250W from wall during gaming, ~350W during Furmark at 40 CU (bytepond, May 2026). Hard limit: 2300 MHz at 40 CU = ~288W. Stay at or below 2200 MHz for safety with 40 CU.
