Why I wanted more
The 4070 Super was a solid card that handled VR racing admirably. It powered my Pimax Crystal Light through most sims at good settings and delivered smooth experiences in typical race scenarios.
But I kept wondering what I was missing. During 24-hour events or multi-class races with 40+ cars on track, I noticed I was leaving performance on the table. The 12GB of VRAM worked well for most situations, but in Le Mans Ultimate with high-resolution cockpits and dynamic weather, I knew there was room to push further.
I wanted to experience VR racing without any compromises. The 4070 Super got me there, but the 5070Ti takes it to the next level.
What the 5070Ti brings to the rig
- 16GB of VRAM gives breathing room for high-res textures and demanding sims like LMU.
- Improved RT cores handle better lighting and reflections without tanking performance.
- Better power efficiency means less heat under load during long stints.
- Frame generation feels more stable than the previous gen, keeping 90fps locked in the headset.
First races with the 5070Ti
- Clarity in traffic: I can now run higher car detail and sharper shadows without dropping frames. Reading competitor numbers and spotting dive-bombs happens earlier.
- Weather performance: Rain in LMU used to cut my frame rate by 30%. Now it stays smooth, and I can focus on driving instead of managing settings.
- Endurance stability: Three-hour races no longer show thermal throttling or micro-stutters. The card runs cooler and quieter than the 4070 Super.
Settings I unlocked
- Raceroom: Maxed out car detail, high shadows, full-resolution mirrors.
- Automobilista 2: Ultra settings with dynamic weather and time progression without frame drops.
- Le Mans Ultimate: Ultra textures, improved reflections, weather effects on high.
- Assetto Corsa with Content Manager: CSP extra FX and Sol weather without compromise.
The 4070 Super delivered great results with smart settings. The 5070Ti removes the need to choose.
Is the upgrade worth it?
If you race in VR and your current GPU forces you to choose between clarity and performance, yes.
The 5070Ti removes the trade-offs. You get sharper visuals, stable frames, and confidence that the hardware won’t bottleneck your driving.
For flat-screen racing, the 4070 Super is still solid. But VR pushes every pixel twice and demands consistent frame times. The extra power matters.
What I learned from the switch
- Sell the old card before the new generation lands. Resale value drops fast.
- Test your most demanding sims first. Automobilista 2 and Raceroom are lighter than LMU, so start with the heavy hitters.
- Don’t chase ultra settings everywhere. Pick what matters for racing: car detail, shadows for depth perception, and stable frames.
Bottom line
The RTX 5070Ti transformed my VR racing setup from “good enough with tweaks” to “run what you want.” Frame drops and setting compromises are gone. I can focus on driving, not GPU management.
For anyone running a 4070 Super (or older) and serious about VR sim racing, this upgrade delivers real-world benefits on track.
