Hey everyone,

I just upgraded my PC and I want to start streaming on Twitch as a hobby. I'd like to do it properly from the start, so I'm asking for your input on the OBS configuration before I commit to settings.

**My specs:**

- CPU: Ryzen 7 9800X3D
- GPU: Gigabyte RTX 5080 Aero
- Motherboard: Gigabyte AORUS Elite Ice X870 WiFi7
- RAM: 32GB DDR5-6000 CL30
- OS: Windows 11 Pro 24H2
- Monitor: ASUS ROG Strix XG32UCWMG (32" 4K 240Hz OLED)
- Internet: 2500 Mbps download / 1000 Mbps upload

**What I want:**

- Variety streamer — mix of single-player, co-op, and competitive games (CS2, Battlefield 6)
- My native monitor resolution is 4K, so I need to downscale to 1080p for the stream

**My questions:**

1. What are the optimal OBS settings for this hardware and use case? Looking for everything — video settings, encoder settings, audio, advanced.
2. Should I configure anything specifically per-game (NVIDIA Control Panel profiles, in-game settings, OBS scene settings) for competitive titles vs casual ones?

Thanks in advance.

My monitor used to run 4K 240Hz over DisplayPort. After upgrading GPU and PSU and reformatting Windows, DP is now hard-capped at 4K 97Hz (which is suspiciously the math max for DP 1.4 without DSC at 10-bit). HDMI 2.1 still gives full 4K 240Hz. The DP issue persists even when I swap back to my old GPU and even when I swap DP cables. Same monitor, same DP port — used to work, now doesn't.

**Hardware:**
- CPU: Ryzen 7 9800X3D
- Motherboard: Gigabyte AORUS Elite Ice X870 WiFi7
- GPU (new): Gigabyte RTX 5080 Aero
- GPU (old, kept for testing): RX 6900 XT
- PSU (new): Endorfy Supremo FM6 1000W
- PSU (old): KRUX Generator 850W
- Monitor: ASUS ROG Strix XG32UCWMG (4K 240Hz OLED, DP 1.4 with DSC, HDMI 2.1)

---

**Timeline:**

1. Original setup (6900 XT + KRUX 850W) — 4K 240Hz over DisplayPort worked perfectly for months.
2. Bought RTX 5080 Aero + Endorfy 1000W PSU. Installed both. Reformatted Windows. Installed Nvidia drivers.
3. Now max refresh rate over DP at 4K is 97Hz. 120Hz appears with an asterisk but only at 1440p. 240Hz simply isn't on the list.
4. Reformatted again, reinstalled drivers — same.
5. Swapped back to RX 6900 XT (with the new PSU) — same 97Hz cap on DP.
6. Connected HDMI 2.1 cable instead of DP — instantly 4K 240Hz, works flawlessly.

---

**Why 97Hz matters:** 97Hz at 4K 10-bit RGB is exactly the theoretical maximum bandwidth of DisplayPort 1.4 *without* DSC. So the symptom is clear: DSC is not being negotiated over DP, even though the monitor supports it and it's enabled in OSD.

---

**Everything I've tried (extensive list):**
- Multiple full Windows reinstalls
- DDU in Safe Mode + clean Nvidia driver install (newest + tried older versions)
- Tried both GPUs on DP (5080 and 6900 XT) — both capped at 97Hz on DP
- **Tried multiple different DP cables — all of them cap at 97Hz on DP** (including the original cable that previously ran 240Hz with no issues)
- All 3 DP ports on the RTX 5080 tested
- Installed monitor INF driver from ASUS (DisplayWidget Center) — monitor IS recognized as XG32UCWMG in Device Manager, not Generic PnP
- DSC Support: enabled in monitor OSD
- Monitor factory reset (multiple times)
- Monitor hard reset (unplugged power for 60+ seconds)
- Type-C Bandwidth setting in OSD changed to USB 2.0
- Tried creating a custom resolution (3840x2160 @ 240Hz, CVT-RB timing) in Nvidia Control Panel — fails to apply
- HWiNFO confirms the GPU is running PCIe 5.0 x16

---

**Current state:**
- DP at 4K → max 97Hz, on both GPUs, on every DP port, with every cable I've tried, after every clean install
- HDMI 2.1 → 4K 240Hz, full G-Sync Compatible, no issues
- Monitor OSD shows the input refresh rate matches what Windows reports

---

**What confuses me:** the problem appeared exactly when I swapped GPU/PSU and reformatted, but it persists even when I revert to the original GPU. The exact same DP cable that worked at 4K 240Hz before now only does 97Hz — and so do all the other DP cables I've tried. I never physically touched the monitor or its DP port during the GPU swap. It's like something in the EDID handshake or DSC negotiation got broken on the monitor's DP input — but a factory reset and a long power-off didn't help. ASUS pulled the firmware download for this monitor from their website (known issue, MCM104 was bugged) so I can't even try a firmware update.

Since **multiple cables and multiple GPUs all fail in the exact same way on DP, while HDMI works flawlessly**, the cable and the GPU side seem ruled out. That leaves the monitor's DP receiver itself — either a partial hardware failure that kills DSC negotiation but still allows a basic DP 1.4 link, or some firmware state I can't reset.

Has anyone seen DSC negotiation "die" on the DP input only, while HDMI keeps working? Any ideas before I RMA the monitor?

Thanks for any help — losing my mind here.

Hi everyone,

I just upgraded my GPU from an AMD RX 6900 XT to a brand new RTX 5080, but I'm running into a massive refresh rate issue that I can't solve.

The setup:

• GPU: RTX 5080 (Fresh Windows install, latest NVIDIA drivers).
• Monitor: Asus ROG XG32UCWMG (Dual Mode: 4K 240Hz / 1080p 480Hz).
• Connection: DisplayPort 1.4 using the original factory cable provided with the monitor.

The problem: On my old 6900 XT, both modes worked perfectly. Now, with the RTX 5080, I’m getting weird caps in both modes:

1. In 4K mode: I am stuck at 4K 97Hz max. If I try to select max 120Hz, the resolution automatically drops to 1440p. 240Hz is missing entirely.
2. In 1080p (480Hz) mode: When I switch the monitor to its high-refresh dual mode, the maximum available setting is only 280Hz.

Important details:

• No settings were changed in the monitor's OSD – it’s still configured exactly as it was when working with the 6900 XT (DSC enabled, DP 1.4 mode).
• I am using the same factory cable that handled the full bandwidth on the AMD card without any issues.
• In NVIDIA Control Panel, I am checking the "PC" section, not "Ultra HD/HD".
• DSR/DSR Factors are turned OFF in the 3D settings.

It seems like the RTX 5080 is failing to trigger DSC (Display Stream Compression) or there is some severe handshake issue between the new DP 2.1a ports and this DP 1.4 display. 97Hz is the exact limit of DP 1.4 without DSC at 4K, so it’s clearly a compression/bandwidth negotiation error.

Has anyone seen this on the new 50-series cards? Is NVIDIA's DSC implementation broken on Blackwell for certain monitors?
