A GTX 1080 or equivalent is more than enough for 1080p 144Hz.240Hz is unattainable with ultra graphics.This is the most you can expect from a processor in rF2 today. It should be noted that disabling Hyperthreading and turning the i7 into an i5 has no effect on performance, so we can conclude that rF2 does not know how to use more than 4 cores and therefore will not benefit from a Ryzen 7 or 9, or one of the new i7 or i9. From the cockpit, the performance is worse, and from the TV camera we get a significant improvement this time, but still below what was invested. Let’s see what happens in a more normal scenario: 1080p Max PracticeĪs we can see, we are facing the same situation. When we switch to the TV view, which is capable of using a 100% 1080Ti, we see a slight increase in FPS but again we hit the limits of the i7, even overclocked at 5GHz, which is unable to use two 1080Ti with all its potential. Adding another one, far from improving performance, makes it worse by having an extra step of communication between the two graphics cards, which are only being used at 40% each. At the ultra graphics level, the i7 is not capable of producing more than 150 FPS on average, and it doesn’t even fully utilize a 1080Ti. What’s going on here? It happens that our 7700K is the limiting factor. And the gains from the TV camera aren’t enough to launch rockets either. From the cockpit to 1080p, not only do we not gain performance, but we lose it. With this, we have rFactor 2 ready to run with SLI. It can also be changed from the Nvidia Control Panel if you prefer. It is not clear if it is a problem of the Nvidia driver or of rFactor 2, but Virtual reality pre-rendered frames must be set to 2 in order to use SLI to its full potential. This last setting, although is strange, is what forces the second card to run at full speed as well. Virtual reality pre-rendered frames: 0x00000002.Nvidia predefined SLI mode: …MODE_FORCE_AFR2.

Nvidia predefined number of GPUs to use in SLI rendering mode: …GPU_COUNT_TWO.Power management mode: prefer maximum performance.Nvidia predefined FXAA usage: disallowed.Once downloaded and opened, we must load the rFactor 2 profile and make the following changes: Motorist users will know it because it’s the only way to apply antialiasing correctly to the simulator since a couple of years ago. To change the SLI configuration we must download a program called Nvidia Inspector. Luckily, the rFactor 2 community has managed to give, based on what surely have been dozens of hours of testing, the right configuration for SLI, and they have been kind enough to share it with the web. In this case, we can see that if we load rF2 with the default profile, the simulator only uses one of the two graphic cards. The problem is that it will be the user who will have to make his own life to configure his equipment and he will not receive any kind of official help, neither from the creator of the game, nor from Nvidia. However, a lot of games, simulators or not, work perfectly with SLI in spite of not having support. rFactor 2 does not have native SLI support, which means that the development team does not recommend its use or work to improve performance. Test conditions: Sebring with 30 GTE at sunset, to gather elongated shadows with abundant reflections and car lights, trying to put as much graphic load as possible.įirst test, first issues.Nvidia’s SLI profile: yes, but inoperative.Before we take action, let’s take a look at the starting situation: Will we be able to finally conquer rFactor 2 in ultra? If you have seen the video above, you will get an idea, but there are many things to test. Although Studio 397 has improved the simulator in the last years, it is still a title that costs a lot to run at full graphic fidelity and it will be a good first test for our SLI. We started our journey by testing rFactor 2, a simulator that has commonly been blamed for poor performance for the level of graphics shown.
