PlayStation 3 Emulator Delivers Modest Speed-Ups with Disabled E-Cores on Intel Alder Lake Processors

According to some testing performed by the team behind RPCS3, a free and open-source emulation software for Sony's PlayStation 3, Intel's Alder Lake processors are enjoying a hefty performance boost when E-Cores is disabled. First of all, the Alder Lake processors feature a hybrid configuration with high-performance P-cores and low-power E-cores. The P-cores are based on Golden Cove architecture and can execute AVX-512 instructions with ease. However, the AVX-512 boost is only applicable when E-cores are disabled as software looks at the whole package. Officially, Alder Lake processors don't support AVX-512, as the processor's little E-cores cannot execute AVX-512 instruction.

Thanks to the team behind the RPCS3 emulator, we have some information and tests that suggest that turning E-cores off gives a performance boost to the emulation speed and game FPS. With E-Cores disabled, and only P-cores left, the processor can execute AVX-512 and gets a higher ring ratio. This means that latency in the ring bus is presumably lower. The team benchmarked Intel Core i9-12900K, and Core i9-11900K processors clocked at 5.2 GHz for tests. The Alder Lake chip had disabled E-cores. In God of War: Ascension, the Rocket Lake processor produced 68 FPS, while Alder Lake produced 78 FPS, representing around 15% improvement.

Intel Disables DirectX 12 API Loading on Haswell Processors

Intel's fourth-generation Core processors, codenamed Haswell, are subject to new security exploits. According to the company, a vulnerability exists inside the graphics controller of 4th generation Haswell processors, happening once the DirectX 12 API loading occurs. To fix the problem, Intel has found that disabling this API results in a fix. Starting with Intel graphics driver 15.40.44.5107 applications that run exclusively on DirectX 12 API no longer work with the following Intel Graphics Controllers: Intel Iris Pro Graphics 5200/5100, HD Graphics 5000/4600/4400/4200, and Intel Pentium and Celeron Processors with Intel HD Graphics based on 4th Generation Intel Core.

"A potential security vulnerability in Intel Graphics may allow escalation of privilege on 4th Generation Intel Core processors. Intel has released a software update to mitigate this potential vulnerability. In order to mitigate the vulnerability, DirectX 12 capabilities were deprecated." says the Intel page. If a user with a Haswell processor has a specific need to run the DirectX 12 application, they can downgrade their graphics driver to version 15.40.42.5063 or older.

GeForce Experience Mandatory Registration, Login and Game Scanning Can Be Disabled

YouTube user TechMax has uploaded a video in which he shows a way to circumvent GeForce Experience's most wanted feature of all time: the mandatory login. One of the least popular features of NVIDIA's most recent GeForce Experience 3.0 update was the introduction of the mandatory logins, meaning that if you didn't, you wouldn't have access to GeForce Experience features, and even the in-app driver update wouldn't be available to you. In case you don't want the green genies to know when you're online, for how long, what hardware you use, and which games you play, and want to make use of the features embedded in NVIDIA's app, watch the video below and follow its steps. You'll need to copy and paste some lines of code, but it shouldn't prove too difficult. You can find the YouTube video below, and a transcript of the steps after the break.

AMD BIOS Signature Check re-enabled with ReLive, Locks out Polaris BIOS Modders

If you are using a modded BIOS on your AMD Polaris card, and try to install AMD's excellent Crimson ReLive drivers, you might be in for a surprise. This is because AMD re-enabled their BIOS signature enforcement with these latest drivers. Basically, if you modded your card's BIOS in search of higher overclocking, more voltage or customized fan settings, the hash in your BIOS is no longer recognized by AMD the driver, since it differs from the factory values.

On detecting such a modded BIOS with an invalid checksum, the Crimson ReLive driver won't load, meaning that the system will run with the VGA fallback driver only, without 3D acceleration and Radeon Settings will not start. However, you can force your modded BIOS to load on Crimson ReLive if you're willing to jump through some hoops.

Watch Dogs 2 Wants to Monitor Your System, But You Need Not Let It Do So

We've earlier reported about the implementation of EasyAntiCheat on Watch Dogs 2 - and how the Ubisoft game installs a driver in kernel mode and a service that monitors your systems' operating files (when Watch Dogs 2 is running). In that piece, we said that "This mechanism is also running even when you're in single-player-only - and even offline - modes, meaning that you're not getting out of its crosshairs no matter how you are playing the game". Now, there seems to be a way to bypass the system monitoring altogether and enjoy the game in single-player. The way to do so, however, varies whether you're running the game on Steam or on Uplay.
