Unreal Engine 4 Linux Tests With AMD & NVIDIA Graphics Drivers
As explained earlier, all of the NVIDIA GPUs ran fine with the NVIDIA 346.22 driver. With the AMD Catalyst 14.12 Omega Linux driver, however, all of the tested GCN GPUs ended up locking-up during the testing process so on the Radeon side were just a few HD 6000 Northern Islands GPUs that successfully ran the tests. Once AMD has corrected these (and the Metro Redux problems) in a future Catalyst Linux release I'll be back with more tests. The GPUs for which there are UE4 Linux results today include:
NVIDIA GeForce GTX 460 768MB (675/1804MHz)
eVGA NVIDIA GeForce GTX 550 Ti 1024MB (951/2178MHz)
MSI NVIDIA GeForce GTX 650 1024MB (1084/2500MHz)
NVIDIA GeForce GTX 680 2048MB (1006/3004MHz)
eVGA NVIDIA GeForce GTX 750 1024MB (1019/2505MHz)
NVIDIA GeForce GTX 750 Ti 2048MB (1019/2700MHz)
NVIDIA GeForce GTX 760 2048MB (980/3004MHz)
NVIDIA GeForce GTX 780 Ti 3072MB (875/3500MHz)
eVGA NVIDIA GeForce GTX 970 4096MB (1163/3505MHz)
NVIDIA GeForce GTX 980 4096MB (1126/3505MHz)
HIS AMD Radeon HD 6450 1024MB (625/667MHz)
Sapphire AMD Radeon HD 6870 1024MB (900/1050MHz)
Sapphire AMD Radeon HD 6950 2048MB (800/1250MHz)
These thirteen graphics cards were tested from a Core i7 5960X Haswell-E system with 16GB of DDR4 system memory, Gigabyte X99-UD4-CF motherboard, 120GB OCZ Vertex 150 SSD. Ubuntu 14.10 64-bit was running on the hardware with the Linux 3.16 kernel, Unity 7.3.1, and X.Org Server 1.16.0.
All benchmarks were carried out using the open-source, cross-platform Phoronix Test Suite benchmarking software.
