I’ve done a lot of tweaking over the last few months, and I think my system is tuned pretty nicely. I know this is a GA plane, flying over terrain without buildings or other AI objects, and not a complex airliner landing at a complex airport, but still…
- AMD 5800X3D (water cooled.)
- MSI B550-A Pro, latest release BIOS - Kombo Strike Level 3, Virtualization OFF, RBAR enabled, Above 4GB GPU enabled, XMP-2, Hyperthreading (SMT) enabled.
- nVidia Driver 531.29 (after DDU clean.)
- EVGA RTX 3090 Ti FTW3 Gaming 24GB (air cooled.)
- 64GB HP V10 DDR4 Samsung B-die (3600 MHz, CAS 14) I’m using a 16GB Ram Drive for MSFS Rolling Cache.
- EVGA SuperNOVA 850 GM, 80 PLUS Gold 850W. (550W draw during this flight.)
About the only other tweaks I’ve done:
Disable HPET in Windows, using Intelligent Standby List Cleaner in place of it.
A few recommended settings in nVidia Profile Inspector.
Game Mode OFF
The sim’s .exe file is set to ‘Normal’ priority. I played around with ‘High’ priority for a while, but I think it gave slightly worse performance.
Great FPS, and even better latency 7-10ms throughout the flight.) If you look at the HW Monitor you’ll see loads and temps for both the CPU and GPU are nicely balanced. One thing I noticed is that the display showed rapid bouncing between ‘Limited By Main Thread’ and ‘Limited by GPU.’ That tells me the two devices are working in a complementary manner.
I don’t ‘chase’ FPS (I’m more concerned with frame time (latency,) but I was seeing 145 fps at one point in this flight.
