Just an F.Y.I. to some folks out there.
I recently obtained a G2 Reverb and was disappointed by the poor frame rates I was getting, (20-24 FPS in MP campaign, 12 FPS in benchmark TE). After trouble-shooting nearly everything, I finally settled on something wrong with the video card, (eVGA 3080 Ti).
Upon using Precision X1 to investigate its settings, it turns out it was set to throttle power at 20%. I know I never set it that way, but it turns out that others in the internets have had similar issues when updating Nvidia drivers with Precision X1 running in the background.
I’ve had the 3080Ti for over a year, and I think it’s been set this way since Day 1. All of my games are now running about 3x more FPS since I set the target to 100% power use so it doesn’t throttle the card. This is what the default target is supposed to be.
I’m now up to ~70 FPS in campaign and ~35 FPS in the benchmark TE with the Reverb G2, with nothing overclocked, (not my 8700k, nor memory, nor GPU) with shadows and environment mapping enabled. Perfectly playable.
Obviously not everyone has an eVGA and uses Precision X1, but it may be worth investigating whether your graphics card is being throttled due to some (not by your wishes) setting.
