Fallout 4 (DirectX 11)
Fallout 4 is set in a post-apocalyptic Boston in the year 2287, 210 years after a devastating nuclear war, in which the player character emerges from an underground bunker known as Vault 111. Gameplay is similar to that of Fallout 3 and Fallout: New Vegas. The player completes various quests and acquires experience points to level up their character. With first-person and third-person perspectives available, players can explore Fallout 4's open world setting at will, allowing nonlinear gameplay. The player can bring companions to assist in battles and help with scavenging. Players have the ability to construct and deconstruct buildings and items, and use them to build settlements, which can attract and be inhabited by non-playable characters. –Wikipedia
Settings used for Fallout 4
All five of our competitors appear to have a solid results in Fallout 4, including the four multi-GPU configurations, which is a welcome start to the review! The green and black lines that represent the Radeon Pro Duo and the pair of R9 Nano cards in CrossFire are essentially identical, matching performance in all respects. The GTX 980 Ti cards in SLI are quite a bit faster, hitting an average frame rate of 125 FPS, 13% faster than the 110 FPS of the Radeon Pro Duo.
When we hit the 4K resolution, things are a bit more important in terms of scaling. The Radeon Pro Duo is almost able to run at 60 FPS, a solid 20% faster than the 295X2. The 980 Ti cards in SLI, though, do run over 70 FPS and also present the most consistent frame times, even compared to the SINGLE GPU Fury X!
|Radeon Pro Duo 8GB, Average FPS Comparisons, Fallout 4|
|R9 Nano CrossFire||R9 Fury X||R9 295X2||GTX 980 Ti SLI|
This table presents the above data in a more basic way, focusing only on the average FPS, so keep that in mind.
Side note: I noticed a strange occurrence with Fallout 4 and the Radeon R9 295X2. As you can see in the screenshot below, CrossFire appears to be interleaving frames out of order on the screen.
The pattern you should see on the screen is teal, blue and then green colored bars on the left side, used for our Frame Rating capture testing. However, the order presented here is teal, blue, teal, green. The frame with the blue overlay on it was presented in the middle of the teal frame, and it results in a very odd distortion – the part of the frame with the dark blue overlay is going BACKWARDS in relation to the animation.
It was apparent while playing that SOMETHING was going on but I had to step through the recordings to find the result. It was frequent and repeatable, but again, only occurred with the Radeon R9 295X2, not the Nano cards in CrossFire or the Radeon Pro Duo.
