Dota 2 moved to the Source 2 engine well before CS2. The 'New Frontiers' update expanded the map by 40%, increasing the load on CPU and memory. Unlike LoL, Dota 2 uses more complex models and lighting. It benefits significantly from the Vulkan API, which distributes load better across CPU cores, though it still relies heavily on main core performance. For stable performance in chaotic 5v5 fights, 16GB of RAM is highly recommended.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 225 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 225 FPS. At 4K, all settings exceed 138 FPS.
The GeForce RTX 4090 is 521% above the recommended GPU (GeForce GTX 960) for Dota 2. The Core i3-1315UE is 41% above the recommended CPU (Core i5-2500K).
The Core i3-1315UE determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
Approximated average price on current market:
Combo price: $1899. At 1080p Ultra, this combo delivers 225 FPS, equivalent to 0.12 FPS per dollar.

At 1440p low, the Core i3-1315UE sets the ceiling at about 225 FPS, while the GeForce RTX 4090 could reach 474 FPS. In this scenario, the CPU limits the GPU potential by 53% (FPS gap: 249 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core i3-1315UE is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 51% | CPU Limits GPU 47% | CPU Limits GPU 41% | CPU Limits GPU 34% |
| 1440p (2K QHD) | CPU Limits GPU 53% | CPU Limits GPU 49% | CPU Limits GPU 42% | CPU Limits GPU 33% |
| 4K (Ultra HD) | CPU Limits GPU 45% | CPU Limits GPU 47% | CPU Limits GPU 42% | CPU Limits GPU 45% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Yes, the Core i3-1315UE paired with the GeForce RTX 4090 can run Dota 2 smoothly up to 4k achieving around 138 FPS at Ultra quality. Your GPU is 521% above the recommended specs, and your CPU is 41% above the recommended requirements.
This CPU + GPU combo costs approximately $1899 ($250 CPU + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 7845HX is a great upgrade option (Rank #1 for value).
For Dota 2, upgrading the CPU would have the biggest impact on performance. The Core i3-1315UE is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Dota 2 does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Dota 2 requires at minimum a Core 2 Duo E7400 (CPU) and GeForce 8600 GT (GPU) with 4 GB RAM and 60 GB storage. For the recommended experience, you need a Core i5-2500K and GeForce GTX 960 with 8 GB RAM. Your Core i3-1315UE and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Dota 2 FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
