 magic_rb | Hm so i bought a 9070xt and playing clair obscur e33, i see that the gpu reports being at 80% capacity, yet its only using less than a third of its power budget. It also just turned off its fans. That seems like its not running at full blast. I can think of two reasons:
- Im running this on a 620w PSU even though the recommended value is 700w
- Im running this on a ryzen 5 2600x
Do you guys know of a way to debug this?
| 08:21:56 |
 marienz | not the former (the GPU doesn't know the wattage of the PSU, if it attempts to draw more power than the PSU can deliver you get system instability). Possibly the latter, especially if you see at least one CPU core running at 100% utilization. | 08:28:44 |
| magic_rb | Nope cpus are at 60ish% | 08:29:21 |
| magic_rb | The mangohud gpu reported wattage doesnt go over 110w. Max is 304 supposedly | 08:31:03 |
| marienz | also, system requirements for that game don't look that steep: with vsync / frame limiter there may just not be more work for the gpu to do (are you experiencing noticeable performance problems or just wanting to make sure you get full value from your GPU?) | 08:31:53 |
| magic_rb | Kinda latter. I did bump the graphics down from epic to high yesterday cause it was dropping frames | 08:33:07 |
| magic_rb | Should try something much worse then, cyberpunk would do i assume | 08:33:38 |
| magic_rb | Yeah it just dipped down to 45 :/ | 08:34:10 |
| magic_rb | Though might just UE5 being shit dunno | 08:34:20 |
| magic_rb | I wanted to test cyberpunk on this anyway, lets see | 08:35:39 |
| magic_rb | This testing is done on jovian btw, so i think radv | 08:37:30 |
 K900 | I bet you're CPU limited tbh | 08:51:41 |
| K900 | Look at per core utilization | 08:51:43 |
| K900 | Not just overall | 08:51:46 |
| magic_rb | It doesnt go over 60% | 09:03:16 |
| magic_rb | Im looking at per core | 09:03:22 |
| magic_rb | I DLed cyberpunk, lets see | 09:04:32 |
| magic_rb | Cyberpunk exhibits the same, 60-70% across all cpus, around 100W on the gpu | 09:12:21 |
| magic_rb | But it runs on rt: ultra at 1080p@60 | 09:17:18 |
| K900 | Do you maybe have vsync/some sort of FPS limit on? | 09:29:42 |
| magic_rb | I mean yes | 09:32:17 |
| magic_rb | Its capped to 60, now it does 45 | 09:32:26 |
| magic_rb | The cpu is at 80% average | 09:32:33 |
| magic_rb | 85% all core, im probably extremely cpu bottlenecked | 09:33:16 |
| magic_rb | Lol okay, cpu bottleneck. Even on steam deck quality i dont get 60fps lmao | 09:46:25 |
| magic_rb | Ig i have to buy a new cpu | 09:46:34 |
| marienz | Or monitor, if your goal is to make the GPU work harder (9070xt probably on the high end in most games at 1080p60) | 10:15:39 |
| marienz | (...to upgrade the CPU you'd end up having to upgrade the motherboard + RAM too, and esp. for RAM now is not a good time to upgrade price-wise) | 10:25:15 |
