[Resolved] TDM doesn't render properly on AMD RX 550

[Dragofer]

Edit: the problem was simply leftover glprogs from an old TDM version.

I've recently "upgraded" my office desktop with a 2nd hand GPU so that it can supply video to 2 modern screens. However, it appears unable to compile GLSL shaders for TDM and is therefore unplayable. As an example, this is what I see on TDM 2.13 or latest 2.14 dev build in Perilous Refuge:

And this is the condump: peril_550.txt

The GPU in question is an RX 550 with 2 Gigabytes of VRAM. It came out in April 2017, so I suppose it should still be able to open TDM. I've installed the latest drivers according to AMD Adrenalin, and never had a GPU or GPU drivers installed in this machine before. The screenshot is identical to what I'm seeing, so to me this suggests the GPU is at fault and not the cables or monitors.

Specs of this PC:

• Make: HP OEM small form factor desktop PC
• OS: Win11 (upgraded from Win10)
• CPU: Intel i5-9400
• RAM: single stick of 8 GB DDR4-2660 CL19
• GPU: XFX RX 550 2 Gb GDDR5
• Motherboard: HP 8653 (proprietary)
• PSU: rated for 180W
• Monitors: P2711 TS QHD x2, via HDMI and DP from the GPU ports
• SSD: INTEL SSDPEKNW512G8H 512 Gb, NVME PCIe x4

Maybe this proprietary HP motherboard isn't designed to be compatible with dedicated GPUs... These days I have better things to run 3D apps on, but maybe solving this case would help improve TDM's compatibility.

Looks like you have some broken packages.

Can you try deleting your tdm_base01.pk4 and any gui pk4's the running tdm_installer

I've removed all .pk4's and ran tdm_installer.exe, but that only got rid of the GUI warnings:

MAX_SHADER_PARAMS is no longer part of our GLSL shader files.

Are you sure there's no glprogs folder somewhere in your install?

Thanks! This was it, the typical old remnants of a dev build causing graphical errors.

Turns out this GPU is surprisingly capable at TDM, rendering the whole Perilous Refuge harbour at 50+ fps @1440p, albeit without fancy settings like AO, soft shadows or shadowmaps. Edit: ran out of VRAM at these settings, unfortunately.

Yeah, 2 GB is really sparse.

A GPU that the wimpy RX 6400 can beat up.
