NVIDIA RTX 50 SERIES - Technical/General Discussion

PhysX does have a footprint in general RAM, it's not entirely GPU bound. But yes I agree with your general points here. As mentioned I'm not sure what if any actual die space has been saved by removing 32bit support, it would be odd to remove it for literally no reason.

More importantly I fully agree Nvidia should have done something. Software emulation or providing a patch for old games PhysX would be the right thing to do. Heck, at least a more detailed statement of why they've done it is better than the silence we've had.

To be clear I'm not defending Nvidia's move, just trying to find some logic as to why they removed the support for it.

Reason is simple, no need for updating the software anymore. Also they did same with SLI.. removed it without warning on 30 series.
 
Nvidia also removed 3D Vision starting from the 30XX generation. ****** me off because I only got a 3D monitor because Nvidia pushed it like crazy for years. The 3D actually worked quite well and finally the hardware was good enough to make 120fps 3D gaming a possibility but then Nvidia just pulled the plug.
 
That's good to hear. I'm getting a 5090 FE too in a couple of days. I was a little worried about the noise but at least it seems like the noise is manageable with enough airflow.

I actually was thinking of getting this case for my new 9950X3D build along with the 5090 FE,


Do you think it'd work alright?

Should work very well for you, great cases :)
 
Good to hear. How are your temps? Memory temps seem to be pretty concerning from the reviews I saw. Very easy to hit 90+c on the memory if running at max power.

Memory temps are low 80's so far. My 3090FE ran far higher memory temps with no issues during the 5 years I had it, so I'm not concerned. 3 year warranty on the 5090FE gives peace of mind.
 
Just got my 5090 Astral installed. These cards are insane.
To play cyberpunk all settings ultra at 4k with path tracing on and get 355 fps (with DLSS 4) is nuts

Not had a chance to tinker yet or set an undervolt, so just running at stock in CPunk the GPU is maxing at 65 degrees, memory 66 degrees, pulling 475w and clock is boosting to 2970Mhz. Idle temp is 46 degrees

The card is fairly quiet, although louder than my previous Zotac, but certainly not loud enough to bother me. Will no doubt be cooler, quieter and less power hungry once I've slapped an undervolt on.

Also nice to have the power cable monitored

Really impressed with the 5090FE. Noise levels are really great. I'm sure it's a little louder than my 4090 Strix in DB terms, but the pitch/frequency really makes it easy on the ears.

I'm not loving the aggressive fan curve for standard desktop/idle use. The fans are on a complete stop (which is good) but as a result the GPU and memory temp slowly rises (I think mostly due to the memory). Once GPU has been above 50°C for a few seconds both fans kick in at 1200 RPM (30%) and run until the GPU has been under 40°C for a few seconds. Then rinse and repeat.

I do plan to undervolt which may help. Failing that, I may need to look into increasing general airflow. I currently have everything else set to be low and slow for desktop use (300-400 RPM).

You can just set the fans so they are on at low / slow / silent speeds when at idle via software. Have you tried this?

I've only just installed and so testing with defaults at the moment. I checked the Nvidia app which has automatic or manual/static options. The minimum on manual is 30% and I think that might also be the minimum for other software.

Try downloading the software ‘Fan Control’ - it really is excellent for controlling case, CPU and GPU fans from a single lightweight program. It also has various options to avoid ramping (such as temps need to be higher for X seconds to warrant an increase).

Edit: yes, your GPU fans may have a ‘minimum spin rate’ - but it’s worth investigating via Fan Control. It will run a test to determine minimum spin rate etc.

355 FPS with 4k path tracing? That is no joke. I assume you are using DLSS4+MFG, do you not get ghosting/artifacting?
 
Multi Frame Generation, a technique that enables the generation of three additional frames for every traditionally rendered frame. This approach results in a significant improvement in frame rates, effectively achieving a fourfold increase in performance.

Fake marketing lies. Frame gen does not increase performance.
I consider FG/MFG a tool, just like DLSS. Turn it on and try it with each game to see whether it make it better or not. What I don't like is that it is false marketed into something it isn't. Just like you said, it does not increase performance. Actually it doesn't really work well under 80 FPS due to input lag. Fluid visuals mean little if the game doesn't respond quick enough, and to top it off, it still needs to be implemented properly by game devs otherwise the image will be full of ghosting/artifacts.
 
I think that most pro reviewers have said that 2X FG works best in terms of a proper balance between artifacts and fluidity. 3X/4X currently generate significantly more artifacts than 2X and thus offers a generally worse experience. But MFG is AI based so my hope is that Nvidia can improve the model enough that artifacts are almost imperceptible when gaming at 240hz or more. Theoretically, artifacts should be harder to spot when the framerate is extremely high.

I would rather have real native frames but I think that frame generation is becoming a necessity because so many modern games are limited by CPU power even when using a 9800X3D. Frame-gen is basically the only solution to maintaining a stable framerate in CPU bottlenecked situations.
 
Installed my 5090 now..
I don't know what to do - I now know what coil whine is..
Is it always that bad on the FE or should I send it back? It is very audible.

From the video can't really hear it too much - But it is incredibly noticeable.

Yeah, coil whine supposedly is quite bad on FEs.

I don't think that they would exchange you a new one for this issue. It's probably considered to be within standard operation.

Supposedly, if you frame-capped the FPS to your screen refresh or lower, the coil whine can be lowered.

If it still bothered you, I think you should probably just sell it and use the profit to get a better AIB.

Just sounds like air movement to me, where's the whine? undervolt and turn your fans down

Perhaps a different case with thicker/more dense side cover could help too. I have a 1000D case and that has a pretty thick and heavy tempered glass cover. It substantially reduced internal noise from fans and GPU. Maybe not a great advice for rapid solution, but if you are sensitive to coil whine you may want to consider investing into a case that cancels out noise better.
 
Been playing a bigger selection of games the noise is just completely off-putting.
There is no way this is normal - The video just sounds like fans but you can hear the constant coil noise.
 
Undervolt and put the case side panel back on. Then try playing a game with usual speaker/headphones setup and see how it is.
