Quick Answer
Yes, the AMD RX 9070 can run Diablo IV at 60fps in 2026 - in fact, it can run Diablo IV well above 60fps at 1440p Ultra settings. At 4K with maximum settings, expect 60-80fps depending on zone density. The RX 9070 is well-matched to Diablo IV's Blizzard engine, which scales efficiently across AMD hardware.
RX 9070 Performance in Diablo IV: What the Numbers Show
The AMD Radeon RX 9070 sits in the upper-mid range to high-end tier of the 2025/2026 GPU market. Based on architectural performance data and Diablo IV's known rendering characteristics, the RX 9070 delivers strong results across all target resolutions.
At 1080p Ultra settings, the RX 9070 pushes well above 100fps consistently, often reaching 140-160fps in open-world areas. This makes it an excellent pairing with high-refresh-rate monitors for competitive Diablo IV play. At 1440p Ultra, expect 80-110fps depending on screen zone and particle effects density. At 4K Ultra, the RX 9070 sits comfortably above 60fps in most scenarios, with occasional dips to 55fps in the most particle-heavy boss encounters.
For South African players running Diablo IV, most will be on 1080p or 1440p monitors, meaning the RX 9070 provides substantial headroom above 60fps without needing to reduce visual settings. Pair it with a gaming PC running a Ryzen 7 or Core i7 equivalent for the best results.
Optimal Settings for Diablo IV on RX 9070 in 2026
Diablo IV's graphical settings are well-optimized and the performance curve is relatively predictable. For the RX 9070 at 1440p, Ultra preset is achievable with all settings on maximum. Shadow quality and Global Illumination are the most expensive settings - if you want to push toward 100fps average at 1440p, reducing these to High (rather than Ultra) costs minimal visual quality while recovering 10-15fps.
AMD FSR 4.0 (supported in Diablo IV as of the 2025 update) is available as an upscaling option if you want to target 4K performance without native rendering overhead. FSR 4.0 Quality mode at 4K produces results very close to native, with significant performance gains. This makes 4K Ultra at 80-90fps very achievable on the RX 9070 with FSR Quality enabled.
Frequently Asked Questions
Does Diablo IV support AMD FSR on the RX 9070? Yes. Diablo IV supports AMD FSR (FidelityFX Super Resolution), and the RX 9070 benefits from FSR 4.0's improved upscaling quality. FSR is a free performance boost with negligible visual downside at Quality and Balanced modes.
Is the RX 9070 worth buying for Diablo IV specifically in South Africa? The RX 9070 is more than capable for Diablo IV and will handle virtually every other current title at high settings. It is a solid all-round investment for a South African gaming build, not just for one title.
Will Diablo IV run at 60fps on lower-end hardware than the RX 9070? Yes. Diablo IV is well-optimized. An RX 6700 XT or RTX 3070 can achieve 60fps at 1080p-1440p Medium-High settings. The RX 9070 simply allows you to target 60fps+ at 4K Ultra without compromise.
