Forza 7 for the PC in benchmark

Forza 7 Benchmark: Vega has more gasoline in the blood than Pascal

Forza 7 for the PC is exclusively available in the Microsoft Store for Windows 10. The game uses UWP and supports only DirectX 12. In the test, the title shows good performance after many negative experiences. And the big surprise: AMD Radeon RX Vega is clearly showing the competition to the start.

 

Forza 7 with UWP, DX12 and beautiful graphics

With Forza Motorsport 7, Microsoft is bringing the first Forza from the main series next to the Xbox One also for the PC. Although for the computer already Forza Horizon 3 (test) given, but belongs to a series.

Forza 7 was developed by Turn 10 Studios and is based on the in-house ForzaTech engine. The game uses only the DirectX 12 API, but only the feature level 11_0 and, like all other DirectX 12 games so far, no new hardware features of the API. Whether Async Compute is used, is unknown, but appears in view of the test results as probable.

 

Forza 7 always looks good

Visually, Forza 7 is on a high level without being able to stand out. Project Cars 2 offers visually more highlights, but also less attractive spots. Forza Motorsport 7 always looks good. The bright colors and the lighting know especially to please, depending on the weather condition but also the reflections (the driver in the front pane) very nice to look at.

The thing with the VSync at UWP

Forza Motorsport 7 is available on the PC only for Windows 10 and only in the in-house Microsoft store – on Steam or other platforms Forza 7 will not appear. The racing game thus uses UWP with all known features

For example, an exclusive full-screen mode is missing, and the overlay does not work with various tools such as fraps. More important, however, is another feature that shares every new UWP game: VSync can only be turned off when the game is set to the native resolution of the monitor. If a resolution other than the native is used, there is always a synchronization between graphics card and monitor, no matter what is set in the game itself. However, since Forza 7 offers integrated down- and upsampling (resolution reduced to 25 percent or increased to 200 percent), there is a way out.

 

Other resolutions can be used for up- and down-sampling with VSync

If the graphics card provides too little performance for the native resolution, it is still set and reduces the internally rendered resolution by upsampling. If the resolution is to be higher than the native, set it down and use downsampling. Then the switched off VSync functions as usual and its use is also recommendable.

The synchronization used by Forza 7 still does not have much fun. If the framerate falls below the refresh rate of the monitor, for example, frames are not displayed, which is expressed by a short jerk. In short, anyone who directly or indirectly does not use the native resolution of the monitor in Forza 7 is faced with technical difficulties. First negative announcements about the performance of the title are often to be attributed to this.

 

A maximum of 30 FPS can be switched off

The PC version of Forza 7 comes with an extensive graphics menu, which allows the game to adapt well to weaker computers. The game offers four different presets (Very Low, Low, Medium, Ultra) under the item “Quality of Dynamic Rendering” as well as an automatic function (recommended), which is based on the own hardware. In the extended graphics options in a separate menu, which must first be activated in the main graphics menu (Dynamic Optimization on Individual), all options can also be customized individually.

There is also a frame limiter (“performance target”). The default setting is 30 FPS. Alternatively there are 60 FPS as well as “enabled”. And “Enabled” turns off. If desired, the Framerate should either be completely unlimited, or be limited to 60 FPS. With a maximum of 30 FPS, both the menu and the game do not feel very good. The frame limiter must always be changed manually. Even the highest preset leaves it at 30 FPS.

 

MSAA is the edge smoothing of choice

Even though it is now very unusual, Forza Motorsport 7 does not support post-processing edge smoothing. Instead, the developer has integrated classic multi-sampling anti-aliasing into the engine, at the stages 2 ×, 4 ×, and 8 ×.

In most modern games, MSAA works best in the best case, but mostly bad. In Forza 7 this is not the case. MSAA processes each visible edge and smoothes it. And it is true: much helps a lot. 4 × MSAA looks better than 2 × MSAA and 8 × MSAA looks better than 4 × MSAA. Significantly better.

Both in 1,920 × 1,080 and in 2,560 × 1,440 should therefore be used 8 × MSAA. And even in 3.840 × 2.160, the highest level visibly looks better than 4 × MSAA. But the result is still not perfect. Who only renders in Full HD, with the flickers even with 8 × MSAA still so much. Starting at 2,560 × 1,440 the picture calms but then clearly, but only from 3.840 × 2.160 drops during the ride no flicker.

 

Edge smoothing – 3.840 × 2.160
Data in frames per second (FPS)

  • AMD Radeon RX Vega 64:
    • Aus
      116,1
    • 2× MSAA
      101,7
    • 4× MSAA
      94,5
    • 8× MSAA
      83,7
  • Nvidia GeForce GTX 1080 FE:
    • Aus
      94,4
    • 2× MSAA
      86,7
    • 4× MSAA
      79,7
    • 8× MSAA
      75,4

The advantage of MSAA is positive that the mode in Forza 7 costs surprisingly little performance. The speed loss is significantly higher than PP-AA but lower than most other games that support MSAA. So 4 × MSAA reduces the performance on a GeForce GTX 1080 by 16 percent, 8 × MSAA costs only another 5 percent. On a Radeon RX Vega 64 the power loss is 19 per cent and a further 11 per cent. AMD loses more speed, but the basic performance is significantly higher.
