Severe FPS fluctuations with XESS frame generation

[丢丢]

Why does the XESS frame generation feature of the Arc A770 graphics card stop working in *Delta Force* when in fullscreen mode? The game requires windowed mode to enable XESS frame generation, yet windowed mode results in severe frame drops with huge fluctuations from over 280 FPS down to around 60 FPS.

Hello @丢丢 !

Thank you for reaching out to the Intel Community. We definitely want you to have the smoothest experience possible while playing Delta Force on your Arc A770! It sounds like you're dealing with a frustrating tug-of-war between display modes and performance.

To get you back into the game with stable frames, we have a few recommendations for you.

Step 1: A Fresh Start with the Latest Driver

We recently released a new driver update (Version: 32.0.101.8724) on April 16, 2026, which includes various optimizations. Before installing it, we recommend performing a "clean" uninstall of your current drivers to ensure there are no lingering conflicts.

1. Use the Display Driver Uninstaller (DDU): Please follow the instructions in our guide here to completely clear out the old driver files: Intel Support: How to use DDU
2. Install the Latest Driver: Once that is done, you can download and install the newest driver specifically for your A770 here: Intel Arc A770 Graphics Downloads

Step 2: Try These In-Game Workarounds

If you find the issue persists even after the driver update, please try these two quick adjustments in your game settings:

• Switch to "Borderless Fullscreen": This is often the "sweet spot" for XeSS Frame Generation. It mimics the look of Fullscreen mode while maintaining the technical compatibility of Windowed mode, which may stop those severe FPS fluctuations.
• Disable "V-Sync": Sometimes V-Sync and Frame Generation can "fight" over how frames are displayed, leading to those big jumps between 280 and 60 FPS. Turning V-Sync Off often allows the AI to do its job more smoothly.

We’re eager to hear if this stabilizes your performance! Please try these steps and let us know the results, we're here to help if you need further assistance.

Warm regards,

I have updated the graphics card driver and disabled VSync. The frame rate no longer fluctuates drastically and frequently as before. However, it still occasionally drops suddenly from around 280 FPS to roughly 120 FPS and then quickly returns to normal. There is still noticeable stuttering, just not as often.

[Resolutions404]

Hello @丢丢 ,

It sounds like you’re making great progress! Moving from constant drops to occasional ones is a big step, but those sudden dips to 120 FPS can still feel like a "hitch" when you're used to that ultra-smooth 280 FPS.

Since you've already addressed the drivers and V-Sync, here is a warm suggestion to help you pinpoint exactly where that remaining stutter is coming from.

A Friendly Suggestion: Ruling out "Network Stutter"

Sometimes, what feels like a graphics card "hiccup" is actually a tiny ripple in your internet connection. In fast-paced games like Delta Force, a momentary spike in Ping or Packet Loss can cause the game engine to pause for a millisecond while it waits for data, which looks almost identical to a hardware stutter.

To help the you narrow this down for you, it might be worth checking a few things:

• Monitor your Ping/Latency: Does the FPS drop happen exactly when your ping spikes? If you see your ping jump from 30ms to 100ms at the same time the frames drop, the issue might be your connection rather than your beautiful Arc A770!

• The "Ethernet" Test: If you are playing on Wi-Fi, try plugging in a LAN cable just for one match. Wi-Fi "jitter" is a very common cause of occasional stutters in Windows 11.

• Check "Reflex" or "Low Latency" Settings: Since you're using Frame Generation, ensure that any "Low Latency" modes in the game settings are enabled, as these help keep the CPU and GPU in perfect sync.

Why the jump from 280 to 120?

Since you are using XeSS Frame Generation, your GPU is working hard to "predict" and create extra frames. If the game server sends a delayed update about an enemy's position, the Frame Generation AI might momentarily "trip" as it tries to reconcile the new data, causing that sudden drop.

You're doing a great job troubleshooting this! If you find that your ping is perfectly stable during those 120 FPS drops, then we know for sure it's something we still need to tweak in the software or Windows settings.

We’re all rooting for you to get that flawless 280 FPS experience! Please let the community know what you find regarding the network stability.

Hello @AlHill ,

I really like that you are keeping an eye on things. I want to tell you that my suggestions are based on my own experiences with the Arc A770.

The reason I mentioned network jitter is that Delta Force is an extraction shooter. In this type of game, server-side desync often causes a frame-time spike because the engine stops to match up player positions. When I use Frame Generation those short pauses get bigger because the AI interpolation buffer collapses, which leads to the big drop in frames per second that the user talked about from 280 to 120.

I am a fellow gamer trying to help someone figure out what is going on with their game beyond just reinstalling the driver. I have to say I am happy that you thought my explanation was good enough to be from an AI program. I am just a person who is sharing what I have learned from trying to fix problems, with the Arc A770.

Hello @丢丢 ,

Thank you for getting back to us! I’m really glad to hear that the previous steps helped improve the situation and reduced the frequency of those major drops, that’s definitely progress in the right direction.

At this stage, I’d like to recommend trying the additional troubleshooting steps shared by @Resolutions404 . Their suggestion is valid, and checking for possible network-related stuttering can be very helpful in narrowing down the root cause of those remaining dips and occasional hitching.

In addition, Intel has just released a newer graphics driver version (32.0.101.8735). I recommend performing a clean installation using the DDU process outlined in my earlier message, and then installing this latest driver from the link below:

Intel® Arc™ Graphics - Windows*

Once the new driver is installed, please test the game again and observe the performance. If the issue still persists, kindly proceed with the network-related checks suggested by Resolutions404 to help rule out any latency or packet-related interruptions.

We look forward to hearing how things go after these steps. If you need any further assistance, feel free to reach out anytime, we’re here to help!

Okay, I'm working on it and will come back to share the results later.

To prevent FPS fluctuations caused by network instability, I launched a match in AI bot mode (with latency steadily maintained at around 26ms with no spikes). XESS frame generation was set to 2x, and the graphics driver version was updated to **32.0.101.8735**. There are no major FPS swings in this test session. However, the low frame rate occasionally drops abruptly to around 20 FPS or even lower, resulting in noticeable stuttering that occurs quite frequently.

To avoid FPS fluctuations caused by network instability, I started a bot match (with latency stable at around 26ms and no fluctuations), set XeSS Frame Generation to 2x, and updated the graphics driver to version 32.0.101.8735.
During this test, there were no major FPS swings, but sometimes the low frame rate (1% lows) would suddenly drop to around 20 or even lower, still causing a noticeable stuttering feeling, and this happened quite frequently.

After updating my graphics card driver, I ran into a new problem: when I open CapCut and click "Start Creating," my system blue-screens.

[Manas_Intel]

Hello @丢丢 ,

It is wonderful to hear back from you! I truly appreciate the effort you’ve put into testing this in a bot match, ruling out network latency was a brilliant move, as it gives us a much clearer picture of what’s happening "under the hood" with the hardware.

Since we’ve stabilized the average frame rates but are still seeing those frustrating drops in the 1% lows (down to 20 FPS), it sounds like we are dealing with a frame-pacing or asset-streaming bottleneck. To get you back to that smooth experience, here are a few specialized steps we can try next:

1. Adjust the Windows "Exploit Protection" Settings

Sometimes, a Windows security feature called Control Flow Guard (CFG) can cause intermittent stutters in high-performance DX12 games like Delta Force.

• Open the Start Menu and type "Exploit Protection."
• Go to Program Settings and click Add program to customize.
• Add the .exe file for Delta Force.
• Scroll down to Control Flow Guard (CFG), check "Override system settings," and turn it Off.
• Restart your PC and see if those 20 FPS dips disappear.

2. Clear the DirectX Shader Cache

Since you’ve updated your drivers several times recently, old shader files might be causing "hiccups" as the game tries to load new ones.

• Type Disk Cleanup in your Windows search bar.
• Select your C: drive.
• Check only the box for DirectX Shader Cache and click OK.
• The game will rebuild these files the next time you play, which may stop the stuttering after the first few minutes of gameplay.

3. Re-evaluate "Resizable BAR" (ReBAR)

For the Arc A770, ReBAR is essential for maintaining stable 1% lows. Please double-check your BIOS to ensure Resizable BAR is reported as Enabled. If it somehow got toggled off during a system update, it would explain why your frames are "tripping" so significantly.

4. High-Performance Power Plan

Ensure your Windows Power Plan is set to "Best Performance" rather than "Balanced." This prevents the CPU from down-clocking during minor lulls in action, which often causes those sudden 1% low spikes.

Next Steps for Technical Review

If the issue persists after trying the steps above, we would like to take a deeper look at your system telemetry:

• CapFrameX Logs: Please provide a log file from CapFrameX during a match where the stuttering occurs so we can review the frame-time data.
• Intel® SSU Logs: Please download the Intel® System Support Utility (SSU) from the link below to generate a system report:
  • Download Intel® SSU for Windows*
  • Note: Before clicking "Scan" and sharing the file, please make sure to uncheck the "Networking" box to protect your privacy.

We are so close to getting your A770 performing exactly where it should be! Please give these a try whenever you have a moment, and let us know if that "hitching" starts to settle down.

I turned off frame generation, and it's now very stable with almost no fluctuation. I don't plan to use this feature in this game anymore. Thank you for your patient answers.
