The Game: Assetto Corsa Competizione
Assetto Corsa Competizione is the simracing simulation available since 2019 from Kunos Simulazioni, who have already proven their potential with the predecessors Assetto Corsa and Ferrari Virtual Academy. A special highlight is the official licensing of the Blancpain GT Series. This includes the official drivers, teams, tracks and cars as well as the various race formats, in particular the 24-hour race at Spa. The tracks included have been laser scanned using the latest methods to ensure maximum accuracy and faithfulness to the original.

The tested graphic settings were in detail:
- Epic with a scaling of 150
- Epic with a scaling of 200
The start of a GT3 race with the Lamborghini Huracan GT3 in starting position 9 with a field size of 20 cars was chosen as the test scenario. At the Nürburgring (3 p.m., cloudy weather), the approximately 70 seconds benchmark time corresponded to the rolling start after the NGK chicane into the Mercedes Arena. On the start and finish straight, two cars were let past, then braked permanently on the right-hand side and continued to hold this side. This is probably by far the most demanding scenario within a race, in the rest of the race you can expect considerably more FPS. An even higher load then probably only occurs during rain or at night.
The test environment
The test system
The following hardware was used as the test system:
- Mainboard: Asrock B450 Pro4
- Processor: AMD Ryzen 5 3600(X)
- Memory: DDR 4 3200 CL15 in dual-channel mode
- Hard disk: Crucial P1 1TB 3D NAND NVMe PCIe M.2 SSD
- Case: be quiet! 500DX
- Power supply: be quiet! PURE POWER 11 600W CM
- Graphics card: GeForce GTX 1080
- Graphics card: GeForce RTX™ 3070 GAMING X TRIO – MSI
- Graphics card: GeForce RTX™ 3080 VENTUS 3X 10G OC
- Display: Samsung LS34J550WQU LED display 86, 6 cm (34.1 inch) UWQHD with 3440 x 1440 pixels.
The test software
For the test MSI’s Afterburner software was used, which provides its own benchmark environment in combination with the Rivatuner Statistics Server. Instructions can be found here: https://linustechtips.com/topic/977649-guide-how-to-setup-msi-afterburner-on-screen-display-using-rtss/
1% low FPS
Even though the Ryzen 5 3600 is not a current high-end processor and is sometimes up to 30% behind the top model Ryzen 9 5950X, some conclusions can still be drawn about the performance of the graphics cards in Assetto Corsa Competizione:
- The Geforce 1080 GTX is noticeably getting on in years. Even at low settings, it is not able to push the processor to its limit, while the two RTX models are still stuck in the CPU limit. At epic settings, the 1% low FPS drops to such an extent that there are sometimes severe jerks during the start-up scenario. This would probably be too great a risk for league operation.
- Even at epic settings, the RTX 3070 and the RTX 3080 are on par with the resolution of 3440 x 1440 pixels used (keyword CPU limit). They manage to calculate an average of almost 100 frames per second and their 1% low FPS is never in a critical range.
- However, if you also activate the scaling factor (which can in some way be transferred to a high-resolution triple-screen setup), the two RTX graphics cards find themselves in a clear GPU limit. While simulation with a factor of 150% is only recommended in an emergency with the RTX 3070, the RTX 3080 offers a clear performance advantage.
- At a scaling factor of 200%, ACC has finally become unplayable for the 3070. The 1% low FPS of the 3080 are also in the critical range, but show the recognisable performance advantage of the RTX 3080 over its smaller sister card.
