April 12Apr 12 It seems that DLSS 4.5 is available for all RTX 30 videocards. But when I try to install/enable it, most of the options are not possible to change and I cannot use it. I would to have suggestions. Thanks.
April 12Apr 12 why not ask chatgpt? Short answer: ✅ Yes — DLSS 4.5 does work on RTX 30-series GPUs. ❗ But not all features, and performance can actually be worse. 🧠 What works on RTX 30 (Ampere) DLSS 4.5 Super Resolution (new AI model) → ✅ supported Ray Reconstruction / DLAA improvements → ✅ supported NVIDIA explicitly states the new transformer-based Super Resolution in DLSS 4.5 is available on all GeForce RTX GPUs, including 20, 30, 40, and 50 series (NVIDIA Blog). 🚫 What does NOT fully work Frame Generation (DLSS 3+) → ❌ RTX 40+ only Multi Frame Generation (4X / 6X) → ❌ mainly RTX 50-only Dynamic Multi Frame Generation → ❌ RTX 50-only (NVIDIA) So RTX 30 cards only get the image quality upgrade, not the big FPS-boosting features. ⚠️ The big catch (important) On RTX 30 GPUs, DLSS 4.5 can actually reduce performance: Heavier AI model → more Tensor Core load Lacks newer hardware features (like FP8 support) Real-world tests show: ~10–20% FPS loss vs DLSS 4.0 on RTX 30 cards (Tom's Hardware) 🧾 Bottom line ✔️ Works: Yes (you can enable it) ⚠️ Worth using? Depends: Use it if you want better image quality Avoid it if you want maximum FPS (especially competitive games) 👍 Practical advice RTX 3060 / 3070 / 3080: Stick with DLSS 4.0 or older presets for performance Try DLSS 4.5 only in single-player / high-quality scenarios AMD 7800X3D, Windows 11, Gigabyte X670 AORUS Elite AX Motherboard, 64GB DDR5 G.SKILL Trident Z5 NEO RGB (AMD Expo), RTX 4090, Samsung 980 PRO M.2 NVMe SSD 2 TB PCIe 4.0, Samsung 980 PRO M.2 NVMe SSD 1 TB PCIe 4.0, 4K resolution 50" TV @60Hz, VR: Pimax Crystal Light + HP Reverb G2 @ 90 Hz, Honeycomb Bravo Throttle Quadrant, be quiet 1000W PSU, Noctua NH-U12S chromax.black air cooler. 60-130 fps. no CPU overclocking. very nice.

Image quality is OK with my 4K television as a monitor. I have RTX 3090 OC.

April 15Apr 15 What exactly do you mean by " But when I try to install/enable it"? Did you install the latest Nvidia driver *and* use DLSS swapper to place it in MSFS's program folder? What are the options that remain unavailable to you? My simming system: AMD Ryzen 5800X3D, 32GB RAM, RTX 4070 Ti Super 16GB, LG 38" 3840x1600

The latest Nvidia drivers are not alwats the best ones. The latest one gave me a lot of stutters and I a very low framerate. I have no program to install it. It is somehow manual and DLSS 4.5 is not available. The maximum is 3.10.
