🎮 DirectX & Vulkan (Graphics Mode)
FullRO's client can render the game two ways: the classic DirectX 9 path, or a modern Vulkan path. Vulkan is enabled by default because it usually gives smoother, more stable frame rates on today's GPUs — most noticeably in crowded towns, MVP fights, and War of Emperium.
You can switch between the two at any time from the FullRO Global Patcher — no reinstall needed.
💡 Not sure which to pick? Leave it on Vulkan. Only fall back to DirectX 9 if your PC is very old or you hit a graphics glitch.
🔀 How to switch
- Open the FullRO Global Patcher (
FullRO Global Patcher.exe). - Click the GFX button on the side rail.
- Choose Vulkan (recommended) or DirectX 9 (Native).
- Close the chooser and press Start to launch the game.
The change applies instantly and sticks until you change it again.
⚖️ Which mode should I use?
| Vulkan (default) | DirectX 9 (Native) | |
|---|---|---|
| Best for | Modern GPUs (last ~10 years) | Very old GPUs / integrated graphics with no Vulkan support |
| Frame rate | Higher & more consistent, better frame pacing | Baseline |
| Crowded maps / WoE | Handles them much better | Can stutter |
| Compatibility | Fixes some black-screen / driver quirks | The original engine path |
| Requirement | A Vulkan-capable GPU (NVIDIA GTX 600+, AMD GCN+, Intel HD 500+) | Any GPU |
⚠️ If you ever see graphical artifacts or the client won't start on Vulkan, switch to DirectX 9 (Native) in the GFX chooser, then update your GPU drivers and try Vulkan again.
🛠️ How it works
Vulkan mode drops a small translation layer (a d3d9.dll) into your client folder that converts the game's DirectX 9 calls into Vulkan in real time. DirectX 9 (Native) mode simply removes it so the game uses Windows' built‑in DirectX 9. Nothing else about your client or characters changes — only how frames are drawn.
For the best results on either mode, keep your GPU drivers up to date.
