AMD’s new GPU driver is reportedly inflicting severe efficiency points with RDNA Three graphics playing cards below Home windows 11, although the bug is a uncommon incidence from what we are able to inform.

One other level to notice rigorously right here is that apparently the issue is barely affecting 3DMark runs, particularly the TimeSpy benchmark (we’ll come again to that later).

VideoCardz (opens in new tab) broke the information {that a} software program engineer at Google (Osvaldo Doederlein) operating an RX 7900 XTX with the newest model 23.3.1 of the Adrenalin driver bumped into bother (opens in new tab) with a lot decrease TimeSpy outcomes than ought to have been produced.

Certainly, Doederlein’s outcomes got here out at greater than 50% slower than regular, a large efficiency loss.

One of many builders at UL (which makes 3DMark) replied to Doederlein to say that they raised the difficulty with AMD, and it gave the impression to be associated to the newest driver model.

The dev noticed: “We additionally checked out our [3DMark] database to check outcomes on the earlier driver vs. new driver on any consequence utilizing 7900XT or XTX and might affirm that this seems to be an actual, if very uncommon situation.

“Amongst all outcomes with the brand new driver, roughly 3% of the outcomes present irregular (very low) scores on Time Spy. No related group of very low scores seem on the outcomes with the earlier driver model.”

Doederlein went on to make clear that they’re operating a take a look at model of Home windows 11 (Launch Preview – so probably the most steady construct), which the 3DMark dev famous isn’t supported by the benchmarking suite.

The developer added that AMD did finally handle to breed this extreme efficiency glitch and that “it’s beginning to look an increasing number of like a driver situation,” with the perfect plan of action for these bothered by the gremlin being to roll again to the earlier driver. Or alternatively to simply sit tight and look ahead to the repair to be deployed.

Evaluation: Greater than meets the attention

There’s a bit extra to this than meets the attention, as additional within the thread on the Steam boards replying to the unique grievance from Doederlein, there’s an RX 6800 GPU proprietor saying they’re affected – so possibly it’s not simply an RDNA Three situation – and that rolling again to the earlier AMD driver model didn’t assist. (The 3DMark dev appears fairly positive that the issue does pertain to the newest AMD driver, although).

Moreover, a few Nvidia RTX 4090 house owners have chimed in saying they’ve been hit, too – however that’s simply two scattered reviews, so add seasoning there. Nonetheless, the commonality right here seems to be operating take a look at variations of Home windows 11. Certainly, a type of RTX 4090 house owners lays the blame on the ft of the preview model of the subsequent large replace for Home windows 11 (Second 2).

Regardless of that, AMD nonetheless believes this bug to be a driver situation, so we’ll follow that as probably the most correct prognosis up to now – though it’s potential that the issue can also be wrapped up in utilizing a preview model of Home windows 11, too.

The extra constructive information is that whoever is being affected right here, it’s seemingly a uncommon bug. The broader concern for these encountering this situation is that possibly it’s slowing down video games in addition to 3DMark benchmarks, and it’s simple to see how people may get paranoid about that chance.

It’s actually one thing that occurred to Doederlein, who in consequence ran a complete bunch of checks on video games. That included benchmarking with Guardians of the Galaxy, Horizon Zero Daybreak, Dying Mild 2, Batman Arkham Knight, Returnal, and extra, however Doederlein discovered no efficiency hit in any way with any of them. So it does certainly look like a benchmarking-only situation solely, fingers crossed – hopefully AMD will shed extra gentle on the bug sooner or later.

What we are able to rule out is that it’s any sort of 3DMark downside, as a result of because the dev clarifies, the TimeSpy benchmark “has not been modified for ages”, so the misbehavior is clearly all the way down to the AMD driver or Home windows 11 (or each together maybe, as talked about).
