VRAM 0/0???

[SqueekyRatter]

Is the game not using VRAM or is this some kind of glitch, I am getting a a lot of stuttering.

No one is disagreeing with that. You are just pushing incorrect statements which is misleading. You must not understand this, its misleading because its not actually happening the way you are describing. Its obviously a UI bug. I’m getting stuttering but I can also run hardware RT. I couldn’t do that if it wasn’t detecting my GPU. I’ve been gaming before the 2000s and common sense says its a UI glitch not what you are describing.

I guess, what I find is there's more suttering with software lumen because it's using the CPU while low hardware lumen is smoother when the load is offloaded to the GPU

Why does the options menu not let me choose anything above 1920x1080? Fix this game!

You can only use software lumen if your card doesn't support hardware ray tracing. That doesn't mean it does it on CPU. It means it does the light bounce on you GPU but not using dedicated Ray Tracing cores. Yes the performance is worse doing it that way so often the accuracy is reduced to compensate at least a bit.

What's the native resolution of your monitor? Because normally it's because that is the native resolution of your monitor which it can detect, rendering a resolution too high for your screen to display without down-scaling would be pointless.

It could also be because your screen has a higher resolution than that but is not correctly detected or has an odd aspect ratio the game doesn't support.

Do you remember GTA4 that would fail to detect our video cards and remain on low settings while displaying our video cards had a maximum of 512 MB VRAM in the in-game settings? It seems just like that exact thing to me. Modern games that run on the UE5 engine need to know what our video card is to enable streaming textures and other settings. There were problems for a while with early versions of Satisfactory (UE5 game) that wouldn't detect people's video cards correctly and had extreme stuttering problems because streaming in areas wasn't working. This is a UE5 game and it seems to do exactly the same thing. I assume the developers will fix this game later.

you're talking out ur ass boy

Software Lumen uses CPU-driven calculations for its dynamic global illumination and reflections. This involves techniques like Screen Tracing, Mesh Distance Fields, and Global Distance Fields, which are processed on the CPU to compute lighting effects.

This is what standards like directX are for, so that a compatible card will be able to do what the software asks of it

Believe what you want.

But on the off chance you want accurate information instead of to argue and assert you are right regardless of the truth.

There is some CPU involvement in software lumen but the calculations are primarily still done on GPU. Support for hardware that had dedicated cores for ray tracing calculations was added after the initial release of lumen into the engine.

I've actually done a little indie development in UE 5.3, and 5.4.

I understand how lumen works a lot better than you, go look it up for yourself.

As for calling me "boy" I'm 50 years old, how about you "son"!

I did look it up, Poindexter

While some recommend switching to Software Lumen to boost FPS, especially on systems with weaker GPUs or those lacking hardware ray tracing support, it often comes at the cost of worse FPS lows and increased stuttering. Here's why:

CPU Bottleneck: Software Lumen offloads lighting calculations to the CPU, which can strain systems with less powerful or older processors. The complex computations for dynamic global illumination and reflections (using Screen Tracing and Distance Fields) are demanding, leading to inconsistent performance, especially in dense scenes with many light sources or geometry.
Frame Time Spikes: The CPU-heavy workload can cause irregular frame times, resulting in stuttering. This is particularly noticeable during scene transitions, heavy combat, or in areas with high object density, where the CPU struggles to keep up with rendering demands.
Optimization Issues: Oblivion Remastered has been noted for spotty optimization, as discussed in community posts on platforms like Reddit and Steam. Software Lumen, while less GPU-intensive than Hardware Lumen, isn't as well-optimized for all CPU architectures, exacerbating performance dips on some setups.
Misleading FPS Gains: Switching to Software Lumen might increase average FPS on GPU-limited systems by reducing the load on the graphics card. However, this often masks the trade-off of lower minimum FPS and stuttering, as the CPU becomes the bottleneck. Users with mid-range or older CPUs (e.g., pre-Ryzen 5000 or Intel 9th-gen) frequently report these issues.

So that's what my problem is. Game's not utilising VRAM

It's my Sony 4k TV. The game is locking me out of any resolution above 1920x1080. It doesn't even show up in the drop down menu. Other games work fine at 4k. I even tried upgrading to the latest Nvidia driver and tried changing settings on the ".ini" files from others who have recommended trying but it doesn't work.

try to force it in the gamesettings.ini file

Sounds like you're using your processor and you have no extra RAM to allocate to video memory.

If you have a dedicated GPU, see if you can force it in the graphics settings under the display settings on Windows. You can get to the display settings on Windows 11 by right click your desktop's background. Set it to high performance to use your dedicated GPU.

Software lumen typically runs better than hardware lumen, due hardware lumen likely using real-time raytracing. Software lumen uses the older tricks for lighting and shadows, like how Skyrim did it, except it's more accurate in UE5. Either way it eats framerate.

Higher "highs" in FPS but worse performance overall unless you're in a situation with a powerful CPU and a very weak GPU without RT cores
