Starcraft 2 has low performance with DXVK on Intel graphics
We kind of do need an apitrace to get an idea of what the game might be doing.
GPU-bound perf in DX9 games is known to be poor in many games on all hardware, but we basically have no clue why since we're not doing anything that's obviously dumb. Although it would be nice to know how it fares on AMD since we basically don't test ANV.
I'd like to have this improved at some point, but we'll probably need help.
The game is free to play, but if you don't want to bother with installing it, I can make an apitrace sometime next week.
As far as I remember, the situation is not so bad on AMD (especially with ACO), there DXVK performs only slightly worse than Nine, but at least they are in the same ballpark. Has been a while since I last tested, so take that with a grain of salt.
I have a laptop with a Vega 10 (3700U), can help with some perf testing.
Can you compile and test the performance with this forked branch? https://github.com/K0bin/dxvk/tree/d3d9-constant-compacting
fwiw, the constant compacting branch has a perf decrease across the board on discrete gpus.
@Venemo Is this still a issue with latest dxvk and drivers?
I don't have a intel gpu but i did some quick tests with a R9 380 & mesa-git on dxvk 1.7.1, 1.10.1 and WINED3D on high settings. The performance seems to have improved a bit since 1.7.1 and is now seems faster than WINED3D. At least on my setup.
@Blisto91 I haven't played anything on the Intel GPU for a very long time. If there is a reason to assume that the situation improved recently, I can re-test.
Rgr. I can't say that it has for you specifically, but there have been some improvements since 1.7.1 so was just interested if you still found the performance unsatisfying compared to the other two.
I'm mostly just checking out old issues 😁
Looks like it doesn't seem to be an issue anymore, at least on my Intel Arc A380 system. I did some quick benchmarks between DXVK 2.3, Master, 1.7.1 and WineD3D.
System:
- CPU: Intel Xeon E3-1270v5
- GPU: Intel Arc A380
- OS/Software: Arch, Mesa git, Sway, wine-ge-25
I used the following settings, which basically set everything the game claims it uses the GPU for to max and everything it claims it uses the CPU for to min, due to my rather weak CPU (not visible in the screenshot, but I also set the game to Fullscreen with a resolution of 1920x1200):
I simply loaded a replay, didn't move the camera at all and wrote down the FPS using the ingame-counter (CTRL+ALT+F) at 1:00, 5:00 and 10:00 minutes in. The replay I used can be found here: https://lotv.spawningtool.com/82416/
I first compared DXVK 2.3 and WineD3D, 2 runs each:
| Time (Run #) | FPS (DXVK 2.3) | FPS (WineD3D) |
|---|---|---|
| 1:00 (Run 1) | ~115 | ~93 |
| 1:00 (Run 2) | ~116 | ~90 |
| 5:00 (Run 1) | ~107 | ~82 |
| 5:00 (Run 2) | ~108 | ~80 |
| 10:00 (Run 1) | ~106 | ~78 |
| 10:00 (Run 2) | ~106 | ~76 |
Next, I tested DXVK Master (specifically this artifact: https://github.com/doitsujin/dxvk/actions/runs/7921308612) and 1.7.1, but only 1 run each:
| Time | FPS (DXVK Master) | FPS (DXVK 1.7.1) |
|---|---|---|
| 1:00 | ~115 | ~74 |
| 5:00 | ~108 | ~70 |
| 10:00 | ~106 | ~67 |
Seems like the performance issue was fixed at some point over the years.
I'm gonna close this then. If this turns out to still be a problem after all, please open a new issue.
Nothing extracted yet.
I have a Dell XPS 13 7390 with the integrated Intel graphics. Starcraft 2 should be playable (even if not perfectly) on medium settings on this machine. However, DXVK has a huge performance discrepancy on this hardware.
The game is free to play, so the easiest way to reproduce this issue is to launch the first mission of the first campaign.
As you can see, in this game DXVK performs slightly worse than even wined3d, and nine straight out blows DXVK out of the water.

There is no graphical glitch, so I don't believe an apitrace is necessary.
